Theresa May has faced sustained questions over cuts to police funding while she was home secretary, since the latest UK attack at the weekend.
Asked whether the Labour leader backed calls – including from former David Cameron aide Steve Hilton – for May to resign over the issue, he said: “Indeed I would, because there have been calls made by a lot of very responsible people who are very worried that she was at the Home Office for all this time and presided over these cuts in police numbers, and she’s now saying that we have a problem.”
Corbyn added: “We’ve got an election on Thursday and that is the best opportunity to deal with it.”
Corbyn had earlier published a statement condemning Saturday night's "appalling acts of terrorism" and praising the work of the emergency services.
On the day followingthe attack he turned his focus on cuts to the police and said: “Our priority must be public safety and I will take whatever action is necessary and effective to protect the security of our people and our country that includes full authority for the police to use whatever force is necessary to protect and save life as they did last night and as they did in Westminster in March."
“You cannot protect the public on the cheap the police and security services must get the resources they need not 20,000 police cuts."
“Theresa May was warned by the Police Federation but she accused them of ‘crying wolf’.”
He also pledged his support for holding the general election on Thursday in a bid to ensure British life continues as close to normality as possible.
“It is the timing of yesterday’s attack that we must also address – today the aim of the terrorists is plainly to derail our democracy and disrupt or even halt this election."
“The general election is of course about the democratic choice between the Labour and Conservative parties and our very different visions and plans for the future of our country."
“But it is also now about something even bigger: it is about the struggle between terrorism and democracy itself."
“The mass murderers who brought terror to our streets in London and Manchester want our election to be halted, they want democracy halted. They want their violence to overwhelm our right to vote in a fair and peaceful election and to go about our lives freely."
“That is why there can be no doubt that next Thursday’s vote must go ahead."
