Up against an insurgent Brexit Party, Momentum activists carpool from all corners of the country to help secure a by-election victory in Peterborough for Labour.
Activists made thousands of calls using Momentum’s distributed phonebank system to mobilise Labour members and persuade swing voters.
Local Labour organisers were overwhelmed by volunteers, with more than 300 people canvassing on the Saturday before polling day and 500 knocking on doors on the day of the vote.
