Labour MP Stephen Kinnock, who has known Jo Cox for 20 years and shared an office with her in Parliament, said her death was "a terrible, terrible waste".

He remembered her coming in dressed in her cycling gear, using his cupboard as a wardrobe. "You knew if you saw Jo at the beginning of the day - your day was going to be a better day," he said.

She was "constantly juggling" the demands of being a mother of two, said Mr Kinnock, and sometimes her children would draw a picture of him when they came into their office.

She "inspired all of the new intake of MPs because she really had the street cred", having travelled overseas as an aid worker, said Mr Kinnock, who described her as "one in a million" who "could never be replaced".

She did get "some creepy messages", he said, adding that "people develop bizarre obsessions and get feelings of violence", and sometimes MPs are the target. But being close and open with constituents "is really an important part of our democratic process".

Mr Kinnock added that his most abiding memory was spending time with Mrs Cox and her family at their little cottage in Monmouthshire and going out on a canoe trip.

Labour MP Jo Cox was receiving "creepy messages" a little while ago - although it's unlikely they were related to the tragic events of yesterday, her colleague and friend Stephen Kinnock has said.

In an emotional interview with BBC's Victoria Derbyshire programme, the Labour MP urged those who write angry posts on social media to "dial it down not just for two weeks but forever".

He also accused the media of "whipping everything up where you can in 140 characters... completely monster somebody in terms of their reputation, personally, their family or as individuals".

Labour former minister Caroline Flint says MPs need to be mindful of the security of their staff.

While meeting constituents is an important part of "our democracy", she says politicians from other countries are sometimes "astonished" with the "up close and personal" contact UK MPs have with constituents.

But for now, she wishes to remember "what a positive person Jo was".

David James is from the Home Office's Fixated Threat Assessment Centre, which examines security risks to politicians and other public figures.

He says: "Around 80% of MPs have been subject to intrusive harassment by constituents - but nearly a fifth of all MPs have suffered some form of attack or attempted attack during their time in Parliament."

Most attackers are "mentally ill loners" with a grievance, he says, and most give some sort of warning such as "threatening letters or difficult visits to a constituency surgery".

His unit was set up so that MPs could refer such threats for assessment but the system does rely on MPs raising the matter. He adds that many MPs see aggression as "just something that goes with the job".

Many MPs feel that they are in some way "shopping" their constituents if they report them, Dr James tells the Victoria Derbyshire programme, but such people are often mentally ill and could be helped if reported.

All campaigning ahead of the EU referendum has been suspended after the killing of Labour MP Jo Cox and David Cameron has said Britain has lost "a great star".

The BBC's James Landale assesses the impact of the murder on political discourse in the UK:

Social media flooded with both praise and criticism of MPs in the hours after Jo Cox's death.

Following the death of Batley and Spen MP Jo Cox, the world's media has descended on Birstall:

The Times' chief leader writer Philip Collins, external remembers the last time he spoke to Labour MP Jo Cox was about his late father.

"He’d spent some time living on a houseboat and that’s where Jo lived, on a boat moored by Tower Bridge, with her husband, Brendan, and their two young children," he said.

"She was kind and the conversation was easy, enjoyable. 'See you,' I said cheerily as I left. But I won’t. Yesterday Jo Cox was stabbed and shot to death, allegedly by a man proclaiming 'Britain first'."

Philip Collins comments that the BBC’s political editor Laura Kuenssberg described her as “brave, funny and clever”, someone who improved your day “if you bumped into her for a cup of tea”.

BBC political correspondent Carole Walker says it's not clear when campaigning ahead of the EU referendum will resume. It is currently suspended as a mark of respect to Jo Cox.

"The campaigns will simply have to try to judge the public mood and decide when they think it is appropriate" to resume the EU debate, Carole says.

The campaign had become "pretty frenetic, pretty personal" and it will be "interesting to see whether the tone remains somewhat subdued and quiet" when the debate resumes, she adds.

There have been "no firm decisions" on recalling Parliament - which is in recess until after the referendum - but MPs may wish to pay tribute in the Commons chamber.

Conservative former leader and EU Leave campaigner Iain Duncan Smith has withdrawn from a head-to-head interview with Andrew Neil.

The interview was due to be broadcast on BBC One tonight.

All referendum campaigning has been suspended in the wake of the killing of Jo Cox.

In the wake of Labour MP Jo Cox's death, the News in Portsmouth, external reports how Donna Jones had vicious threats made against her as leader of the city council.

The paper says Cllr Jones had been to police about attacks on her, which included threats to cut her throat. She urged the government to consider tougher action to stop "keyboard warriors", saying that internet abuse could rise to horrifying levels.

Labour's Anna Turley joins her fellow MP Clive Betts to pay tribute to Jo Cox on the Victoria Derbyshire programme.

Like Jo Cox, Ms Turley was first elected to Parliament in the 2015 general election. She says many new parliamentarians are "shocked and taken aback at how much aggression there is towards MPs".

She adds that security "needs to be looked at but Jo would not want us to be hidden, behind walls".

Labour MP Clive Betts says .Jo Cox "had a great future ahead of her" and persuaded people with her arguments by being "a genuinely nice person".

"She was just so full of life and determination," he told BBC's Victoria Derbyshire programme, adding that she had " so much passion, so much intelligence... such an enormous loss".

Mr Betts said MPs always had to be careful and sensitive about security "but we have to be there for our constituents when they need it".
