Police in Britain are staying tight-lipped over reports of a plot to kidnap Prime Minister Tony Blair’s youngest son. It seems former members of “Fathers 4 Justice”, a group campaigning for the rights of divorced fathers, were considering snatching five-year-old Leo Blair.Police apparently foiled the plot in its very early stages last month. The Sun tabloid newspaper broke the story today. Matt O’Connor, who founded Fathers 4 Justice, has denied all involvement: “We are appalled as an organisation,” he said. “We spent three years campaigning to make sure children see their fathers and here is a story that says that people on the periphery of our organisation are talking about kidnapping a five-year-old boy. “I can’t think of anything more appalling or traumatic.” Fathers 4 Justice have staged some high profile stunts to highlight their cause including scaling London landmarks in superhero outfits. Their campaign aims to highlight what they see as an unfair restriction of fathers’ access to their children in custody disputes. But the group says it has now halted its activities and would consider shutting down if it was hijacked by militants.
