An MP has died after she was shot and stabbed during an attack in her constituency, police have said.
Jo Cox, 41, Labour MP for Batley and Spen, was left bleeding on the floor by her attacker. A 77-year-old man also suffered slight injuries.
A 52-year-old man was arrested near Market Street, Birstall, West Yorkshire Police said. The MP held a weekly advice surgery nearby.
The MP's death was confirmed at police headquarters in Wakefield.
Police said they were not looking for anyone else in connection with the attack.
Labour leader Jeremy Corbyn said the country would be "in shock at the horrific murder", describing the MP as a "much loved colleague".
Lord, have mercy on the soul of Jo Cox
You may recall, I recently posted a link to an article written by Jo Cox. On the subject of immigration and the EU referendum. In tribute to her, I will re-post it here:
The Yorkshire Post: Brexit is no answer to real concerns on immigration
Jo Cox believed in the kind of Britain I believe in, a welcoming, inclusive country that is a part of Europe and the rest of the world.
