Jeremy Corbyn has defended his decision to adopt a neutral stance in a future Brexit referendum as “a sign of strength” and “maturity”.
The Labour leader told a BBC Question Time leaders’ special on Friday that he would not campaign for Leave or Remain if his party wins power.
Prime Minister Boris Johnson questioned how Mr Corbyn could be “indifferent” on such a vital issue.
And Lib Dem leader Jo Swinson accused him of an “abdication of leadership”.
But Mr Corbyn said acting as an “honest broker” was a “sensible way forward”.
If he becomes prime minister, Mr Corbyn has promised to negotiate a new Brexit deal with the EU and put this to a public vote alongside the option of Remain.
However, in Friday’s programme he confirmed he would maintain a neutral stance in this referendum before carrying out the result.
Speaking on a campaign visit to Sheffield on Saturday, Mr Corbyn said: “I think being an honest broker and listening to everyone is actually a sign of strength and a sign of maturity.
“Our country has to come together – we can’t go on forever being divided by how people voted in 2016.
“My role as the Labour prime minister would be to ensure that [another referendum] is carried out in a fair way, that the offers put are fair, and that I will carry out the result of that referendum.
“I think this is actually a sensible way forward that can bring people together.”
What have the other parties said?
Health Secretary Matt Hancock said Mr Corbyn’s stance “won’t wash” with voters, adding that the Labour leader had “decided to be indecisive” on the “critical question of our times”.
“You can’t ask the public to be prime minister of this country when you can’t even make your mind up on Brexit,” he told the BBC.
Speaking during Friday’s Question Time special, Mr Johnson said the Labour leader’s ambition to negotiate a new Brexit deal would be undermined by his neutral stance.
“I don’t see how he can do a deal when he is going to be neutral or indifferent,” he said.
During a campaign visit in west London on Saturday, Lib Dem leader Jo Swinson said Mr Corbyn’s position was “astonishing”.
“On the biggest issue faced for a generation, they are not going to take a position,” she said.
“Remainers in this country need a leader, not a bystander.”
