Jon Lansman and two fellow Momentum-backed colleagues have achieved an overwhelming victory in elections for three new places on the Labour Party’s ruling body.

Mr Lansman, Yasmine Dar, a Manchester councillor, and Rachel Garnham, a national policy forum representative, won all three positions available on the National Executive Committee (NEC) today.

The result has bolstered Labour leader Jeremy Corbyn’s control of the party, potentially smoothing the way for rule changes and possibly the reselection of MPs.

They each received more than 60,000 votes from party members, with comedian Eddie Izzard finishing in fourth place with 39,000 votes.

The trio had won backing from the Centre Left Grassroots Alliance, which is made up of left-leaning factions, including the hard-left Momentum group and the Campaign for Labour Party Democracy.

Mr Lansman tweeted: “Really honoured to now represent almost 600,000 members on the national executive of @UKLabour - at last the 21st century version of the Socialist party I joined 44 years ago.”

Committee members who had previously rebelled against Mr Corbyn, including the party’s deputy leader, Tom Watson, have announced they will no longer challenge his authority after Labour’s surprisingly strong result in the 2017 general election.

Mr Lansman was born into an Orthodox family in Southgate, north London, and spent part of his teenage years working on kibbutzim in Israel.

After graduating from the University of Cambridge and Birkbeck, University of London, he became a prominent member of the Campaign for Labour Party Democracy and later worked for Tony Benn, before establishing Momentum, which has heavily backed Mr Corbyn.

Speaking at the Limmud Festival last month, Mr Lansman said he felt antisemitism was a problem for all political parties to tackle, rather than one confined to the Labour Party.

All nine places on Labour’s NEC will be voted on later this year.
