A journalist has offered ISIS £50,000 to fight him after posing outside Parliament with a sword in a bizarre stunt.

Andre Walker, a columnist for the New York Observer, posted a picture of himself with his cutlass on Twitter outside the House of Commons.

He said: 'A bounty on my head. Any #ISIS terrorist that kills me gets £50k. I'll give my address. No police. But I've got a sword. Good luck.'

Walker posted the Tweet from the Westminster terrace, a popular bar for politicians and journalists

The bizarre stunt took place just 12 hours after three jihadi fanatics killed seven and injured 48 in central London.

However Walker, who has spent his career covering Parliament as a Lobby Correspondent, was quickly mocked for his ill-timed stunt.

Jeffrey Peel responded on Twitter: 'Not sure what point you're making with this.'

Walker responded: 'They are cowards who blow up kids and run people over. I'm suggesting a fair fight...with me.'

He later said that he would be 'changing his will on Monday.'

Walker had previously worked for Breitbart as a political journalist

People immediately started saying the post was insensitive, while others simply continued mocking him.

The former Breitbart writer told the Mirror he stood by his tweet.

He said: 'As a freeman of the City of London I have a sword. And my offer to any terrorist is this: why don't you pick on someone your own size.

Twitter users were quick to mock Walker's bizarre stunt

Walker maintained that he was 'up for it' and said he wanted terrorists to 'pick on someone their own size'

'It's an act of frustration and I repeat the thing. £50,000 for anyone who wants to fight me. I'm up for it.'

Labour Parliamentary candidate for Redcar Anna Turley said: 'Parliament please can you refer this to parliamentary authorities.'

Dean Van Nguyen tweeted: 'Have a day off mate.'

Twitter user Jeff Greenspan said that Walker had made the terror attack 'all about you'

Tim Burrow said: 'I deal with some right clowns in my day job (criminal defence solicitor), but even the dimmest look like Einstein compared to this one.'

Steven O'Brien added: 'It's worrying this clown has a job based in the House of Commons. May be for not much longer.'

Jeff Greenspan added: 'Congratulations on making a terror attack all about you.'
