Lewisham East byelection: Janet Daby wins but Labour's majority cut by Lib Dems

Liberal Democrats leapfrog Conservatives into second place in seat that voted heavily for remain in the EU referendum

Labour’s Janet Daby has won the Lewisham East byelection after only 33.4% of eligible voters cast their ballots. The party suffered a swing to the Liberal Democrats, who leapfrogged the Conservatives to come second.

The byelection was triggered by former Labour MP Heidi Alexander’s decision to quit Westminster to take up a job with the London mayor, Sadiq Khan.

Alexander had a majority of 21,213 in the south-east London constituency at the 2017 general election. The Conservatives finished second in 2017 with the Liberal Democrats a distant third.

For the byelection, the Lib Dem leader Vince Cable campaigned in the seat for the party’s candidate, Lucy Salek, with the party confident of an improved performance in a constituency that voted heavily for remain in the EU referendum.

In the end, the Lib Dems succeeded in reducing Labour’s majority from nearly 45% to 25.6% and pushed the Conservatives into third place.
