Yvette Cooper has reported a death threat to her children and grandchildren made in response to her campaigning to remain in the EU.

The Labour MP for Pontefract and Castleford shared a threatening tweet with her followers that was sent on 21 June, stating: "Got this today for speaking out for Remain..... This has to stop."

The tweet said: "Hello, Yvette I have received your Stronger In propaganda emails 5 times please stop or I will kill your kids and grandkids."

Cooper said she had reported the threat to the police, and the account it came from has been suspended.

Responding to concerned followers who asked if the problem was being dealt with, Cooper wrote: "Yes, reported hours ago. Police & @Twitter on case. But this is for all of us. Time to stop the hatred."

The threat comes less than a week after the murder of Labour MP for Batley and Spen, Jo Cox. The mother of two, who was also a Remain campaigner, was stabbed and shot outside her constituency surgery in Birstall last Thursday (16 June).

Cox had reported a number of threats made against her to the police, and a man had been arrested in March – although this was not 52-year-old Tommy Mair, who has been charged with Cox's murder.
