Jeremy Corbyn addresses meeting on formation of new leftwing party

Exclusive: Ex-Labour leader gives speech at event where organisers say they aim to start party named Collective

Jeremy Corbyn has addressed a meeting for a new leftwing political party named Collective attended by the former Unite general secretary Len McCluskey and a number of former independent candidates.

Key figures in the group said they hoped the party would act as an incubator for future leaders who could replace Corbyn as a figurehead of the left, and aim to contest seats at the next general election.
