LIVERPOOL, United Kingdom (AFP) — Newly re-elected British Labour leader Jeremy Corbyn called for unity Sunday in his deeply divided party, but risked antagonising his own lawmakers by promising more power to his grassroots supporters.

The veteran left-winger was confirmed in his position on Saturday with 61.8 per cent of the vote among party members and supporters, seeing off a challenger backed by most of his more centrist lawmakers, who believe he can never lead them into government.

The main opposition party remains bitterly split between left-wingers and moderates, at a time of major change in Britain as Prime Minister Theresa May’s Conservative government negotiates the country’s withdrawal from the European Union.

In his acceptance speech at the party conference in Liverpool, northwest England, Corbyn pledged to “wipe the slate clean” after accusations of bullying and fears of an irreparable breach in the century-old movement.

The 67-year-old said Sunday he was “reaching out” to his critics — but his proposal to give more decision-making power to party-members risks being seen as an attempt to sideline MPs.

“What I want is more power for members, more power for supporters, in order to ensure we get policies that do have support throughout the whole party,” he told BBC television.

“There’s a lot of thirst for change out there, people want to see things done differently.”

Labour’s membership has soared to around 600,000 since Corbyn became leader last September. His victory over challenger Owen Smith was driven by the new members, exit poll data shows.

But their fervour is not reflected in the wider electorate.

An ICM poll for The Sun newspaper put the Conservatives on 41 per cent, Labour on 26 percent and the pro-Brexit UK Independence Party on 14 per cent.

A ComRes poll for the Sunday Mirror found that 16 per cent of voters thought Labour was likely to win the next general election under Corbyn’s leadership, against 65 per cent for May’s Conservatives.

Many moderate MPs publicly accepted Corbyn’s re-election and backed his call for unity, but the anonymous briefings against him continued in Sunday’s newspapers.

In a sign of the entrenched divisions, Labour peer Lord Parry Mitchell resigned from the party saying it was a “lost cause” under its current leadership.

He blamed Corbyn for being “lukewarm” about tackling anti-Semitism in the party and condemned his left-wing supporters.

“Jeremy has no leadership qualities whatsoever — his little group like him and they think he’s the Messiah, but he will never become the leader and prime minister of this country,” he told the BBC.

Corbyn said Mitchell’s comments were “unfortunate” but that “actually the party is very united” on policy, citing its opposition to Conservative plans to bring back academic selection in schools.

He urged MPs to “move on and discuss policies”.

But Corbyn did not rule out the possibility that some of his critics may lose their seats in a forthcoming redrawing of Britain’s constituency boundaries, amid speculation that his supporters are planning to use the rejig to oust hostile MPs next time candidates are selected.

Sadiq Khan, who as London mayor is Labour’s most senior elected official, warned against any purge of moderates — or indeed the establishment of an anti-Corbyn group within the party.

“If the Labour Party splits, it could be the end of the party,” he told The Sunday Times.

More than 40 MPs resigned from Corbyn’s shadow cabinet in a rebellion in June sparked by the Brexit vote, which critics said the leader should have campaigned harder to prevent.

Reports suggest a dozen may now return to the front bench, although many prominent figures are likely to stay away.

MP Lucy Powell, who had served as Corbyn’s education spokeswoman, told The Observer newspaper that the party was “more divided than I have ever known”.
