The Brexit Party is pressing ahead standing candidates in Labour-held seats that the Tory party needs to win for an overall majority in the election. Nigel Farage’s supporters say that the Tories were presumptuous in assuming that the Brexit Party should stand aside. Rupert Lowe stood down in Dudley North, where former Labour MP Ian Austin stood aside. At the last election, Labour had a majority in the seat of 22. It voted 67.6% leave. In a closely-fought campaign these decisions could make all the difference. Where are the top ten Labour marginals – in order of most marginal – in England in which a Brexit party candidate may complicate voting patterns and change the result?
