The husband and two young children of Jo Cox gathered with her friends in Trafalgar Square for a vigil on what would have been her 42nd birthday. The Labour MP was stabbed and shot dead outside a constituency surgery in Birstall less than a week ago.

Her widower Brendan and the couple's two young children left their home, a houseboat along the Thames, and travelled by boat up the river to prepare for the rally. They towed a small flower-covered boat named the Yorkshire Rose as a memorial to the campaigner.

Memorials will also be held in Cox's home town of Batley and in Huddersfield. A tribute will be set up at the Glastonbury festival, while several bands involved in the annual event are set to contribute towards a charity album in her name. A Go Fund Me page set up in Jo Cox's name by her family and friends has already raised more than £1,290,000, with an eventual target of £1.5 million.

Events are planned around the world on what would have been her birthday, with a candlelit vigil held at a charity centre in Syria, and events planned in New York, Washington, Paris and Brussels.
