A campaigner scaled London Mayor Boris Johnson's home this/yesterday (Mon) morning dressed as comic book hero Iron Man in his latest stunt to protest at what he sees as a lack of rights for dads.

Bobby Smith was joined on the balcony of the Mayor's house by fellow campaigner Martin Matthews to highlight a perceived lack of equality over contact with their children in the event of a divorce.

Mr Smith - who claims to have been denied access to his children for six years - was making his second visit to Mr Johnson's house after a previous protest there fell on deaf ears.

He and Mr Matthews hung up banners around Mr Johnson's London home and shouted down to supporters using a megaphone.

Mr Smith, who stood against Prime Minister David Cameron at the last General Election dressed as the Muppet character Elmo, said: "I'll just keep coming back till he's ready to talk. He'll give in before I do."

The 33-year-old from Stevenage, Herts., said: "It's no good sitting at home getting depressed and getting upset at how much you miss your kids. You need to stand up and not accept what has happened.

"There's no equality for fathers in family law. I want nothing less than a legal presumption of equal contact for a child with their parents if they split up.
