<\/picture><\/span><\/div>\n<\/figure>\n<\/div>\nThe Labour Party would need a record swing in votes at the next general election to win a majority in the House of Commons, according to analysis of the new electoral map. <\/b><\/p>\n<\/div>\n<\/div>\n The next election will be fought on new constituency boundaries, redrawn to reflect population changes and to try to even out voter numbers in each area.<\/p>\n<\/div>\n<\/div>\n An analysis of these changes for BBC News, ITV News, Sky News and the Press Association suggests Labour needs a national swing of 12.7% to win with just a small majority. <\/p>\n<\/div>\n<\/div>\n That’s considerably higher than the 10.2% achieved by Tony Blair in 1997 and higher even than the 12% achieved by Clement Attlee in 1945.<\/p>\n<\/div>\n<\/div>\n The swing from the Conservatives to Labour would need to be uniform, to follow the same pattern everywhere, with other parties seeing no change in performance since 2019. <\/p>\n<\/div>\n<\/div>\n In practice, the picture will be more complicated, so this is a rough guide. But a uniform national swing has been a reliable model for general elections in the UK over a long period of time.<\/p>\n<\/div>\n<\/div>\n Changes to the political map ahead of the next general election mean constituencies will be new or different from the last general election for millions of people.<\/p>\n<\/div>\n<\/div>\n The boundary changes could have an impact on who becomes the local MP and which party wins the UK’s election overall.<\/p>\n<\/div>\n<\/div>\n You can use our tool to find out which constituency you are now in.<\/p>\n<\/div>\n<\/div>\n It will also give you an estimate of what the result would have been had these new boundaries been in place at the last general election, in 2019.<\/p>\n<\/div>\n<\/div>\nBoundaries changed<\/span><\/h2>\n<\/div>\n
