Momentum forms the backbone of the campaign to re-elect Jeremy Corbyn as Leader of the Labour Party. Borrowing ‘big organising’ techniques from the Bernie Sanders campaign, hundreds of activists host ‘Campaign Call Outs’, pop up phone-banks in their homes inspired by ‘Bernie’s ‘Barnstorms’.

These local meetups result in over 100,000 calls made, using the ‘Call for Corbyn’ phone-canvassing app. Thanks to this nationwide effort, Jeremy Corbyn is re-elected with an increased mandate.
