TWO Fathers 4 Justice campaigners dressed as comic book heroes, including Jolly Stanesby from Ivybridge, scaled the roof of Deputy Labour leader Harriet Harman's house in London yesterday.

The demonstration was intended as an “early Father's Day strike” against the Government over fathers' access to their children, the protesters said.

Fathers 4 Justice named the pair as Mark Harris and Jolly Stanesby, from south Devon, and said they were dressed as “Captain Conception” and “Cash Gordon”.

The group claimed that another two activists were inside Ms Harman's home in Herne Hill, south London, and had 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'.

Fathers 4 Justice founder Matt O'Connor said: “Harriet Harman and the Government have refused all dialogue with F4J for the past two years. We are now resuming a full-scale campaign of direct action against the Government, its ministers and the judiciary. F4J is now the last line in the defence of fatherhood.”

A Scotland Yard spokeswoman said: “We were alerted at 8.51am to reports of two males on the roof of a residential address in Herne Hill. Officers are currently in attendance at the location and are speaking to the men.”
