A former member of the British National Party (BNP) is to contest the Batley and Spen by-election following the death of Labour MP Jo Cox.
In the days after Cox's death the Conservatives, Liberal Democrats and Ukip all announced their intention not to stand in the by-election.
However Jack Buckby, a member of Liberty GB, said Labour had "blood on its hands", and there was "too much at stake" to allow them to retake Batley and Spen unchallenged.
It's fair to say quite a lot of people on Twitter have something to say about Buckby's announcement, and his chances of being elected.
Meanwhile, Buckby's announcement has also been criticised as "inflammatory" by the Green party group leader on Kirklees council.
Councillor Andrew Cooper said: "If we have learnt anything in the last few weeks and certainly in the last few days, it is that people need to be more respectful to people who have different and contrasting views."
Buckby, 23, who is a former BNP member and stood for election for Liberty GB in the 2014 European elections, said: "We cannot let Jo Cox's tragic death be in vain.
"We must use this election as an opportunity to create dialogue and give a voice to the millions of working and middle class Britons who are seeing their communities trashed by an arrogant and out-of-touch political class."
His announcement comes after Cox's sister called for people to show "strength and solidarity" in the wake of her death.
Cox died on Thursday after being shot and stabbed as she was due to hold a constituency surgery at a local library in Birstall.
A 52-year-old man who appeared at Westminster Magistrates' Court in London on Saturday over the killing gave his name as "Death to traitors, freedom for Britain".
Thomas Mair, from Birstall, is charged with murder, grievous bodily harm, possession of a firearm with intent to commit an indictable offence and possession of a knife.
