The 41 year-old labor MP leaves behind two children and husband, Brendan Cox.

Just before lunchtime on Thursday, British MP Jo Cox was brutally attacked and killed by 52 year-old Thomas Mair outside her constituency surgery in Birstall in northern England.

According to police reports, Cox was punched and kicked to the ground by Mair before being shot three times, including once in the head, before being stabbed at least seven times with a hunting knife.

Witness, Clarke Rothwell, told the Press Association the attacker repeatedly shouted “Put Britain first” while shooting Cox.

Though Police are yet to comment on the motives behind the attack, Mair was thought to support far-Right causes and suffered from mental health issues, known as a loner to his neighbors.

“He lived by himself. He’s been on his own for about 20 years,” neighbor David Pickles, told the Yorkshire Evening Post.

It’s also emerged that Cox had received an increasing number of threats and harassing messages over the past three months and was in the midst of seeking additional security from law enforcement before the attack.

Cox’s husband Brendan, with whom she has two young children, aged three and five released a moving statement shortly after her passing.

‘[This] is the beginning of a new chapter in our lives. More difficult, more painful, less joyful, less full of love. I and Jo’s friends and family are going to work every moment of our lives to love and nurture our kids and to fight against the hate that killed Jo.’

Described as a rising political star, the mother of two is the first British MP to be murdered in office since Conservative MP Ian Gow was assassinated in a 1990 car bombing.
