A fathers’ rights protestor who was jailed for two months after scaling deputy Labour leader Harriet Harman’s Herne Hill home dressed as a super hero has failed in his bid to have his conviction overturned.

John Paul Stanesby, 43, a qualified childminder from south Devon, along with fellow protestor Mark Harris, spent more than 24 hours on the roof of the cabinet minister's home in Winterbrook Road on June 8.

Dressed as superheroes "Captain Conception" and "Cash Gordon" the protestors from campaign group Fathers 4 Justice unfurled a banner from a bedroom window reading "A Father is for life, not just conception".

The campaigners said they intended to remain at the property until the minister read Mark Harris's book, Family Court Hell, and the Government started dialogue with the campaign group about doing more to protect fathers in the family courts.

Last month Stanesby, who was found guilty of causing distress and alarm and refusing to obey a police officer, was jailed for two months, fined £250 and ordered to pay £500 costs at City of Westminster Magistrates’ Court.

At Southwark Crown Court on Wednesday, he challenged his conviction and sentence saying he had been on the phone and had not heard what was being asked of him by police.

But Judge James Wadsworth rejected his appeals and upheld an Asbo banning him from trespassing on private property.
