Britain First leader Paul Golding has condemned the attack on Jo Cox MP as 'an attack on the very fabric of this country'.

After it was reported the shooter chanted "Britain First" during the attack, Mr Golding said it was too early to speculate - but added: "Could this person have shouted 'it's time to put Britain first?'"

The leader of the far right movement said: "She has been out campaigning to keep Britain in the EU and there are people in the area that are against it.

"An MP is in hospital fighting for her life. It's disgraceful.

"I don't think it was one of our supporters. We stand in elections and organise protests - we don't encourage this kind of nonsense.

"She has a young family - an attack on a mum like that is disgraceful.

"Whether you agree with Labour, to have had that happen to her on the streets is shocking and an indictment of the state of this country.

"God bless her and I hope she does get better."
