Election result wherein a party or candidate wins by a large margin
A landslide victory is an election result in which the winning candidate or party achieves a decisive victory by an overwhelming margin, securing a very large majority of votes or seats far beyond the typical competitive outcome.[1][2] The term became popular in the 19th century to describe a victory in which the opposition is "buried",[1] similar to the way in which a geological landslide buries whatever is in its path. A landslide victory for one party is often accompanied by an electoral wipeout for the opposition, as the overwhelming support for the winning side inflicts a decisive loss on its rivals. What qualifies as a landslide victory can vary depending on the type of electoral system, as the term does not entail a precise, technical, or universally agreed-upon measurement. Instead, it is used informally in everyday language, making it subject to interpretation. Even within a single electoral system, there is no consensus on the exact margin that constitutes a landslide victory.[1]
A landslide victory implies a powerful expression of popular will and a ringing endorsement by the electorate for the winner's political platform. A landslide can be viewed by a winning candidate or party as a mandate or a tacit authorization from the public to implement their proposed policies and pursue their agenda with confidence. Emboldened by the result, the winner may undertake ambitious reforms or significant policy shifts to reflect the electorate's desire for meaningful change.[3] However, it can also indicate deep political polarization in an electorate[4] or an unfair election.[5]
A combination of factors, including charismatic leadership, a favorable shift in public sentiment driven by dissatisfaction with or support for the status quo, strategic electoral campaigning and a positive media portrayal, can create the conditions necessary for a landslide victory. A landslide may fundamentally reshape the political landscape of a country; one example of this phenomenon is Franklin D. Roosevelt's election as US president in 1932.[6] In a post-landslide scenario, a winning party can sometimes implement its policies with little resistance, while its severely weakened opposition may struggle to perform essential checks and balances.
2021 Western Australian state election – Mark McGowan led the Labor Party to win 53 out of the 59 seats in the lower house. The Labor Party had a primary vote of 59.92% and a two-party-preferred vote of 69.68%. The National Party won 4 seats and the Liberal Party won 2 seats, making the National Party the official opposition, the first time they had held this status since the 1940s. To date, the election is the most decisive result at any Australian state or federal election since Federation, in terms of both percentage of lower house seats controlled by the governing party (89.8%) and two-party preferred margin.[10][11]
In a Canadian federal election, a landslide victory occurs when a political party gains a significant majority of the House of Commons of Canada.
Landslide victories may also occur during provincial elections, and territorial elections in Yukon. Landslide victories are not possible for territorial elections in the Northwest Territories, and Nunavut, as its members are elected without reference to political parties, operating as a consensus government.
National landslide victories
The following Canadian federal elections resulted in landslide victories:[13]
1935 – The Liberals, led by William Lyon Mackenzie King, won 171 seats (an increase of 34) and gained a majority of 50, while the Conservatives, led by R. B. Bennett, won just 39 (a decrease of 98).
1940 – The Liberals, led by William Lyon Mackenzie King, won 179 seats (an increase of 6) and gained a majority of 56 seats while the Progressive Conservatives, led by Robert James Manion, won just 39 (unchanged from their previous share).
1949 – The Liberals, led by Louis St. Laurent, won 191 seats (an increase of 73) and gained a majority of 59, while the Progressive Conservatives, led by George A. Drew, won just 41 (a decrease of 25).
The vote by province in 1958 shows the scale of the Progressive Conservatives' landslide victory.
1958 – The Progressive Conservatives, led by John Diefenbaker, won 208 seats (an increase of 96) and gained a majority of 75, while the Liberals, led by Lester B. Pearson, won just 48 (a decrease of 57).
The vote by province in 1984 shows the scale of the Progressive Conservatives' landslide victory.
1984 – The Progressive Conservatives, led by Brian Mulroney, won 211 seats (an increase of 111) and gained a majority of 69, while the Liberals, led by John Turner, won just 40 (a decrease of 95). Mulroney is the only prime minister to have won a majority of seats in every single province.
1993 – The Liberals, led by Jean Chrétien, won 177 seats (an increase of 96) and gained a majority of 29, while the Bloc Québecois, led by Lucien Bouchard, which ran only in Quebec, won 54 (an increase of 54). The ruling Progressive Conservatives, led by Kim Campbell, won just 2 (a decrease of 154).
In the 2022 Gujarat Legislative Assembly election the governing Bharatiya Janata Party won a landslide victory of 156 seats of the 182 seats in the state (85.7%), the most ever won by any party in Gujarat's history and securing 52.50% of the total votes polled. No other political party could win enough seats to be recognised as official opposition in the state.
In the 2024 Maharashtra Legislative Assembly election the governing Bharatiya Janata Party led Maha Yuti alliance won 235 of the 288 seats in the state in a landslide. It was the biggest victory recorded in the state. The Bharatiya Janata Party on its own won 132 of the 149 seats it contesting recording a 88.59% win percentage. No other political party could win enough seats to be recognised as official opposition in the state.
In 2025 Haryana local elections, in Faridabad Municipal Corporation, Bharatiya Janata Party candidate Praveen Joshi polled 4,16,927 votes, securing roughly 80.6% of the valid votes in a contest against the Congress candidate (who received 1,00,075 votes). This margin of 3.16 lakh votes is cited as the highest-ever for a mayoral election in India.
Until 1996, New Zealand used the traditional first-past-the-post system as in the U.K. to determine representation in its Parliament. Thus, landslide elections at that time were defined in an identical fashion, i.e. where one party won an overwhelming majority of the seats. Since 1996, New Zealand has used the mixed member proportional system as in Germany, making landslides much less likely.[23]
In UK general elections, a landslide victory involves winning a large majority in parliament and often goes with a large swing from one party to another as well. Landslide victories have usually occurred after a long period of government from one particular party and a change in the popular mood.[37]
Large majorities, however, are not always the advantage they appear to be. Anthony Seldon gives a number of examples of the infighting that can arise from large majorities. He claims that a "sweet spot" parliamentary majority of 35–50 seats is enough to protect from by-elections and still comfortably pass legislation.[38]
Notable landslide election results
1906 – Henry Campbell-Bannerman led his Liberal Party to victory over Arthur Balfour's Conservative Party who lost more than half their seats, including his own seat in Manchester East, as a result of the large national swing to the Liberal Party (The 5.4% swing from the Conservatives to Liberals was at the time the highest ever achieved). The Liberal Party won 397 seats (an increase of 214) and a majority of 124 seats, while the Conservative Party were left with 156 seats (a decrease of 246).[39][40]
1945 – Clement Attlee led the Labour Party to victory over Winston Churchill's Conservative Party, a 12.0% swing from the Conservatives to Labour. Labour won 393 seats (an increase of 239) while the Conservative Party were left with 197 (a decrease of 190).[41]
1983 – Margaret Thatcher led the Conservative Party to win a landslide victory (her second term in office) with 397 seats (an increase of 58, the party's highest seat count since 1931) and a majority of 144 seats, while the Labour Party led by Michael Foot won 209 seats (a decrease of 60). Additionally in the popular vote the party finished just two points ahead of the SDP–Liberal Alliance. However, they receive far more seats due to the first past the post system.
1997 – Tony Blair led the Labour Party to win a first landslide victory with 418 seats (an increase of 146) and gained an overall majority of 179 while the Conservative Party led by John Major won 165 seats (a decrease of 178).

The election led to 54 Labour seats changing to Conservative predominantly in the Midlands and Northern England – some of which had been held by Labour since the first half of the 20th century.[44]
2024 – Keir Starmer led the Labour Party to win a landslide victory with 411 seats (an increase of 211, the party's highest seat count since 2001) and a majority of 172 seats, while the Conservative Party led by Rishi Sunak won 121 seats (a decrease of 251, the party's worst ever result, exceeding the previous worst defeat of 1906.[45])
A landslide victory in presidential elections occurs when a candidate has an overwhelming majority in the Electoral College. In federal and state congressional elections, a landslide victory occurs when a party wins 60% or more of the seats in a legislative chamber.
