A British Jewish journalist is being trolled online following a BBC radio interview on Tuesday in which Labour Party leader Jeremy Corbyn was stumped by her questions about childcare policy.

Appearing on BBC Radio 4’s “Women’s Hour” program, Corbyn — who is seeking to upset Prime Minister Theresa May’s Conservative Party in next week’s parliamentary elections — was unable to provide host Emma Barnett with figures on the price of Labour’s free childcare plan.

“It will cost… it will obviously cost a lot to do so, we accept that,” Corbyn stammered, according to the BBC.

After the interview, Corbyn supporters attacked Barnett on social media, the Daily Mail reported.

On Twitter, one commenter, Steven McNamara, called Barnett a “Zionist shill” and compared her looks to those of the Muppet character Miss Piggy.

Another Twitter commenter, Mary-Anne Penniman, questioned Barnett’s motives, writing, “You honestly think someone who routinely tows Israeli line this (sic) is an impartial and appropriate person to interview a left wing politician?”

In response to her critics, Barnett tweeted, “So abuse from @jeremycorbyn supporters begins. He didn’t know his figures plain & simple.”
