Friends of murdered MP Jo Cox are hoping to help three charities.

A statement from her office named them and urged people to donate via a gofundme page.

In less than four hours more than £50,000 was donated.

Police are still holding a 52-year-old man in connection with her death.

The statement said: “In celebration and memory of Jo Cox, her friends are raising funds to support three charities closest to her heart, chosen by her family.

“The charities are:

The Royal Voluntary Service, to support volunteers helping combat loneliness in Jo’s constituency, Batley and Spen in West Yorkshire.

HOPE not hate, who seek to challenge and defeat the politics of hate and extremism within local communities across Britain.

The White Helmets: volunteer search and rescue workers in Syria. Unarmed and neutral, these heroes have saved more than 51,000 lives from under the rubble and bring hope to the region.

“In her husband Brendan’s words: ‘Jo believed in a better world and she fought for it every day of her life with an energy, and a zest for life that would exhaust most people. She would have wanted two things above all else to happen now, one that our precious children are bathed in love and two, that we all unite to fight against the hatred that killed her.”
