The 25-year-old man arrested over the death of Sir David Amess has been named in the media.

The man arrested on suspicion of murder following the brutal stabbing of the Tory MP has been named as Ali Harbi Ali, according to Whitehall officials, cited by the BBC's security correspondent Frank Gardner.

The suspect is understood to be a British national with Somali heritage who wasn't known to security services ahead of the attack.

According to a Whitehall source cited by the Guardian, he was said to have been previously referred to the government's Prevent scheme aimed at tackling radicalisation.

Detectives have been granted a warrant of further detention at Westminster Magistrates’ Court which allows them to hold the suspect until October 22, Scotland Yard said.

Tributes from politicians across the political spectrum have poured in since the shocking attack on the dad-of-five on Friday afternoon.

Hundreds of people carrying lanterns and candles were seen gathering for a vigil at a sports ground in the MP's constituency this evening.

Sir David, 69, who represented Southend West in Essex, was attacked by a man who walked into Belfairs Methodist Church, where the MP was hosting a constituency surgery.

The suspect had booked an appointment to see the MP before he was stabbed to death, witnesses said.

The Metropolitan Police said his death is being treated as a terror incident, with a potential link to Islamist extremism.

The force believe the suspect acted alone and are not seeking anyone else in connection with the matter.

Inquiries into the circumstances of the incident are continuing.

Sir David's wife Julia, four daughters and son are grieving in private as they still haven't made any public statement following the tragedy.

But the MPs cousins left a tribute at the scene where he was killed, with a message reading "we can't believe this".

It read: "RIP David. Thinking of your lovely family. Can't believe this has actually happened.

"We will always love you. Cousins Moira and Pat."

It comes after Boris Johnson and Keir Starmer stood side-by-side today to lay flowers for Sir David.

The Prime Minister and Labour leader united in Leigh-on-Sea, Essex, after the second fatal stabbing of an MP during constituency work in six years.

They were joined by Commons Speaker Sir Linsday Hoyle and Home Secretary Priti Patel, who laid floral wreaths and stood briefly in silence outside Belfairs Methodist Church, where Sir David died yesterday.

Boris Johnson has spoken of the “shock” and “sadness” around Westminster and the country, while the flag at Downing Street was lowered at half mast following the attack.

Speaking in Downing Street, the PM said the UK had lost a "fine public servant" in Sir David and one of " the kindest, nicest, most gentle people in politics".

He added: "He also had an outstanding record of passing laws to help the most vulnerable."

Following the attack, Speaker of the Commons, Sir Lindsay Hoyle said: "In the coming days we will need to discuss and examine MPs’ security and any measures to be taken, but for now, our thoughts and prayers are with David’s family, friends and colleagues."

MPs return to the Chamber on Monday.

Sir David is the second MP to have been killed doing their job after Labour MP Jo Cox was murdered in 2016.

Brendan Cox, Jo's widower, said the stabbing was "as cowardly as it gets".

He tweeted: "Attacking our elected representatives is an attack on democracy itself. There is no excuse, no justification. It is as cowardly as it gets."

The incident has caused shockwaves to spread through the usually quiet seaside neighbourhood.

Sir David had been an MP since 1983, first for Basildon and since 1997 for Southend West.

He was a well-known backbencher who never held a ministerial or shadow ministerial post during his 38 years in parliament, instead campaigning on issues including animal rights.

He was considered to be on the right of the Tory party and opposed bills furthering LGBT rights, including equal age of consent and same-sex marriage.
