Membership at Central Suffolk and North Ipswich Labour has swelled since the 2015 General Election, according to its former PPC.
Jack Abbott, of Debenham, who came second to Dr Dan Poulter at the election, said 165 people have signed up as fully-fledged members of the local group since May, a 73.3 per cent increase.
Mr Abbott, who said he is backing Liz Kendall in the Labour leadership contest, told the Diss Express: “I welcome the huge number of people who have signed up locally and nationally not least many young people.
“My message would be this; don’t let this leadership campaign be the first and last time you get involved in the party and in politics. Get involved in your communities, make your voice heard, bring about a positive change.”
When asked about the media’s coverage of candidate Jeremy Corbyn, who is set to appear at the Burston Strike Rally on Sunday, September 6, he responded: “He has certainly engaged with a significant portion of our membership and has also attracted an element of support from outside the Party particularly from previous Green Party supporters and some former Labour members.
“I would say however that whoever wins the election I will be out campaigning just the same and I hope that other members and supporters will also join me no matter the outcome.
