A white supremacist carried out the “political” murder of Labour MP and Remain campaigner Jo Cox after conducting internet searches on fellow Remainer William Hague, and Ian Gow, an MP killed by the IRA, a court heard.

Thomas Mair, 53, shouted “Britain first, this is for Britain” as he shot and stabbed the MP for Batley and Spen a week before the EU referendum, a jury at the Old Bailey in London was told.

Mrs Cox tried desperately to defend herself as she was shot three times and stabbed 15 times in a “brutal” and “cowardly” pre-meditated attack.

When Mr Mair was stopped by police 20 minutes later, he held up his hands and told them: “It’s me … I am a political activist,” it is claimed.

Mr Mair denies murdering Mrs Cox on June 16 this year, as well as three other charges relating to the attack.
