Thousands of Twitter users have taken part in the #ThankYourMP hashtag to show their support to their local politicians in the wake of the murder of Labour MP Jo Cox. The hashtag became one of the top trending topics on Twitter in the UK as many took the opportunity to thank their MP for the under-appreciated work they do.

The morning after the death of Cox, the hashtag was reported to have been used in more than 10,000 tweets, peaking at a rate of nearly 40 a minute.

The hashtag followed the shooting and stabbing of the MP for Batley and Spen after holding a constituency surgery in Birstall, West Yorkshire. Tributes have since been paid to the 41-year-old mother of two, described by David Cameron as a "star in Parliament" and a politician who had a "lifelong record of public service and a deep commitment to humanity" by Labour leader Jeremy Corbyn.

Members of the public also laid down flowers, candles wreaths and messages of condolences in Parliament Square in Westminster the morning after she was killed on 16 June.

Confirming her death, West Yorkshire's Police and Crime Commissioner, Mark Burns Williamson, said: "My thoughts and prayers are with Jo's family at this time. I have worked closely with Jo since she was elected and I am deeply shocked that such a talented young woman has been senselessly attacked and killed whilst working in her constituency and serving her community.

"This is a truly shocking incident but I want to reassure communities that our information is that this is a localised incident, albeit one that has a much wider impact.

West Yorkshire Police have arrested a 52-year-old man in connection with the murder, believed to be local man Tommy Mair, and are not looking for anyone else in connection with the incident.
