In Parliament for little over a year, Jo Cox had already carved out a reputation as a plain speaker and solid operator.

Relatively young by political standards, Ms Cox was due to celebrate her 42nd birthday next Wednesday and had been spoken of as a future Minister.

Ms Cox was a Remain supporter in the referendum and both official campaigns have suspended their operations as a mark of respect following the attack on her.

The mum-of-two was elected in May 2015.

Since she was elected to her home town constituency she had made sure she had been at the centre of the community in her Batley and Spen constituency.

She held the Batley & Spen seat in May 2015 which had been vacated by Mike Wood, increasing the majority by 2,000 to just over 6,000.

On her Twitter page she described herself as “mum, proud Yorkshire lass, boat dweller, mountain climber and former aid worker.”

Just 24 hours ago she had tweeted out that her husband Brendan and children were taking part in the so-called battle of the Thames where Bob Geldof had a high profile rant against Nigel Farage.

Ms Cox was born in Batley and educated at Heckmondwike Grammar School and then Cambridge University.

She was head of policy for Oxfam and an advisor to Sarah Brown and Baroness Kinnock. She was national chair of Labour Women’s Network and a senior advisor to the Freedom Fund, an anti-slavery charity.

According to the Labour Party: “Jo became the first in her family to graduate from university, finishing her degree at Cambridge University in 1995. Her career has involved working all over the world for charities fighting to tackle poverty, suffering and discrimination. She has worked with Oxfam, Save the Children and the NSPCC both here in the UK and in some of the world’s poorest and most war-torn regions.

“A dedicated campaigner nationally and locally, Jo focuses heavily on fighting for our public services, particularly against the decision to downgrade Dewsbury and District Hospital. She is also involved with efforts to strengthen our manufacturing base in Yorkshire and in campaigns and initiatives to tackle poverty and the cost of living crisis, such as Batley Food Bank.”

Ms Cox had been a vocal advocate for the victims of the Syrian civil war and was chairwoman of the All Party Parliamentary Friends of Syria group.

The MP abstained in last autumn’s contentious vote on allowing British military action in Syria, insisting a more wide-ranging attempt at a solution to the conflict was needed.
