Alastair Campbell compared ISIS terrorists to Brexit-supporting newspapers today as he lashed out at Theresa May's response to the London attacks.

Tony Blair's former spin doctor lashed out at the PM after she delivered a defiant response to the marauding terror attack in London Bridge last night.

Mrs May set out a four point plan to end 'tolerance' toward Islamic extremism that she said was fuelling the spate of terrorism to hit Britain.

Mr Campbell, in a tweet he has since deleted, said: 'Mrs May is happy enough to tolerate the extremism of the Brextremist Lie Machine newspapers spewing hate day after day.'

Mr Campbell, who remains a Labour activist and journalist, came under a storm of criticism for his tweet.

After deleting the message he added: 'Previous tweet deleted. Agreed it was over the top.

'But was genuinely angry at Mrs May's speech which was highly political and ill judged.'

Mrs May addressed the nation from Downing Street this morning after convening the Government's emergency committee just hours after the brutal attack.

The Prime Minister said the three attacks in the past three months were not directly connected but were linked by the 'the single evil ideology of Islamist extremism'.

In her speech, Mrs May said: 'In terms of their planning and execution the recent attacks are not connected.

'But we believe we are experiencing a new trend in the threat we face as terrorism breeds terrorism and perpetrators are inspired to attack not only on the basis of carefully constructed plots after years of planning and training.

'And not even as lone attackers radicalised online but by copying one another and often using the crudest means of attack.

'We cannot and must not pretend things can continue as they are. Things need to change and they need to change in four important ways.'

Shadow foreign secretary Emily Thornberry criticised the Prime Minister's 'political' intervention on a day when the parties had agreed an election truce.

She told the BBC World at One programme: 'I don't think it's right to get dragged into plans at this stage so soon after those attacks.

'I do think this is a matter of timing.'

Asked if the announcement strayed into party politics, she said: 'I think that it is drawing us into a debate.

'I think that there is time enough for us to discuss this issues.

'As I say, I don't think that anything she is proposing is anything that needs to be or will be dealt with tomorrow.

'I don't think there is any immediate steps she is putting forward and obviously if it was then that would be a different matter.

'To come out onto the steps of 10 Downing Street, immediately in the aftermath of a terrible outrage like this, was not something that would be expected.

'I just simply regret the approach that she has taken.'
