At the EU referendum held on 23 June 2016, Doncaster voted to leave the European Union. This was a contrast to the views of the constituency's MP Ed Miliband, who advocated a "Remain" vote. Miliband was re-elected on 12 December with a significantly reduced majority of 2,370 votes at the 2019 general election, which is attributed to Brexit Party candidate Andy Stewart picking up 8,294 votes and finishing in third place with 20.4% of the vote. Following the collapse in the Labour vote, the seat is now marginal between Labour and the Conservatives.
