The leader of UKIP has said his party has been "vindicated" on immigration and security issues in light of recent terror attacks in the country.

In a speech in Westminster, Paul Nuttall told the audience that he was "only sorry that this vindication has come too soon and has involved so much blood being shed".

Mr Nuttall said UKIP had been the only party "with the guts to tell it how it is" and called Theresa May "complacent at best" for her time in the Home Office.

But he said his criticisms of the prime minister "pale into complete insignificance in comparison to the the prospect of Jeremy Corbyn or a Diane Abbott government".

Fast food chain KFC has confirmed that Khuram Butt worked for one of its franchises.

"We will cooperate fully with the police's ongoing investigation and cannot comment any further at this stage."

Former deputy prime minister Nick Clegg has said the idea that internet companies should act as a censoring authority is "wholly unreal".

He said it is "the job of lawmakers and governments" to police illegal activity online.

When asked by Martha Kearney if he should have opposed cuts to police numbers under the coalition government, Mr Clegg said "we had to rescue the British economy".

Theresa May is speaking at a campaign event in Stoke. She has praised the emergency services for their swift response to the attack and mentioned the powers of the security services.

However, Mrs May also told the Sun that President Trump's state visit would still go ahead. The date is still to be confirmed.

Foreign Secretary Boris Johnson said although he was not personally familiar with the details of who the third attacker was, he said the police and MI5 will be looking at all the details.

"I've worked with them, the security services, very closely over the last eight years when I was Mayor of London.

"I thought they did a fantastic job. I think they continue to do a fantastic job. If there are lessons to be learned from this event then of course we will learn them.

"But it is vital they are allowed to get on with their work, that they are properly supported."

The prime minister says she expects police and security services to launch a review as more details emerge of the attackers from Saturday night.

In an interview with Sky News, Theresa May said she "recognised people's concerns" after it was revealed at least one of the attackers had been known to UK authorities.

"MI5 and the police have already said they would be reviewing how they dealt with Manchester and I would expect them to do exactly the same in relation to London Bridge," she said.

Italian police sources have confirmed London Bridge attacker Youssef Zaghba was on a watch list.

The 22-year-old Moroccan-born Italian was stopped at Bologna airport in March 2016 when he was on his way to Turkey, due to concerns he might travel to fight in Syria.

Material about the so-called Islamic State was found on his phone.

Italian sources told the BBC that the database which Zaghba was on would have been shared with British security forces.

The newly elected mayor of Derry City and Strabane District Council Maoliosa McHugh led a minute silence in Guildhall Square to the victims.

Sarah Denton from Manchester said she went ahead with her planned trip to London as she had arranged it weeks ago and did not expect an attack to happen.

"We carry on", she said, as she laid down a bouquet of flowers following the minute silence held at London Bridge.

• The third attacker has been named by police as Youssef Zaghba, a Moroccan-Italian man who lived in east London. He was not a police or MI5 subject of interest
• Another victim has been named as Australian Kirsty Boden, who her family said ran towards London Bridge in an effort to help people
• A minute's silence was held across the country for the victims
• A row has erupted over police funding between Labour and the Tories ahead of Thursday's election
• A 27-year-old man was arrested under the Terrorism Act at about 08:00 BST

The gym where Khuram Butt trained in Ilford has posted a statement on its door after it was revealed he was one of the attackers involved on Saturday.

The Ummah Fitness Centre in St Luke's Avenue said it was currently closed because of recent media activity.

The statement said: "While Mr Butt did occasionally train here at UFC gym we do not know him well nor did we see anything of concern, we will of course help the police in any way we can."
