In the 2017 election, UKIP did not contest the seat but endorsed the Conservatives. Clive Lewis increased Labour's vote share by 22 percentage points to win 31,311 votes (61.0%), the most votes any party has ever won in the constituency. This happened despite the Conservative share of the vote also increasing by 7.1%. The swing was entirely from the Liberal Democrats (who had held the seat from 2010 to 2015) whose vote fell to 5.5%, and the Green Party (who had made the seat a top target in 2015) who dropped to 2.9%, their worst result in Norwich South since 1997.
