Jeremy Corbyn has insisted that his MPs are not under any threat within Labour's conference in Liverpool.
His comment came after Jewish MP Luciana Berger was pictured flanked by police protection as she attended an event on the fringe of the annual gathering.
Ms Berger was provided with protection after police carried out a risk assessment. The decision was made after threats and abuse were directed at the MP in the wake of her criticisms of the Labour leadership's handling of the anti-Semitism row.
In an interview with Channel 4 News, Mr Corbyn was shown pictures of the Liverpool Wavertree MP and asked whether he felt concerned that she felt under threat attending her own party's conference.
He replied: "There is no threat being made in this conference to anybody."
A Labour spokesman later pointed out that the Jewish Labour Movement rally where Ms Berger received her police escort took place in a venue outside the conference area.
The spokesman said: "We support whatever security is necessary for any of our MPs.
"We have had one fatal incident involving one of our MPs. There have been extremely serious threats made against our MPs - including Jeremy, in the case of the trial of the killer from Finsbury Park - from far-right white supremacists."
"We take these threats extremely seriously and we work with the police and security services to do whatever is necessary to protect our MPs."
