Momentum hold mass canvassing events in the constituencies of splinter group MPs (later of Change UK) to build support for Labour in the event of a by-election and inform constituents that their MP has left Labour and joined a coalition with former Tory MPs instead.
Events involved an afternoon of canvassing followed by a social and were held in Streatham, Stockport and Penistone and Stocksbridge – the constituencies of Chuka Umunna, Anne Coffey and Angela Smith.
