Jo Cox was a force of nature, a five-foot bundle of Yorkshire grit and determination absolutely committed to helping other people.

I first met her shortly after she came into the House of Commons for the first time last year. She came to see me to talk about international development, the issue she’d done so much work on.

She said she wanted to set up a new parliamentary group to talk about Syria and the appalling situation there.

What was so striking about that was that here was a newly-elected Labour MP who had so little time for the petty aspects of party-political life of Westminster.
