Britain's most wanted paedophile is to be extradited from Ireland to the UK despite a "cynical" attempt by his brother to block it.

John Richard Murrell fled to Ireland after serving half of a two-year sentence for sexually assaulting a nine-year-old girl, breaching the terms of his release. The Worcestershire man is wanted by West Mercia Police.

The Irish High Court yesterday ordered the 39-year-old be sent for trial in England even though he faces a charge in a Dublin court.

The summons, for failing to notify gardai of his whereabouts, was issued in the name of Murrell's brother, Alan.

Ordering the extradition Mr Justice Michael Peart accused the brother of cynically attempting to abuse the legal system.

"Even if I was satisfied that there was some merit in the case, my view would be that it quite clearly was such an abusive attempt ... that it would be unconscionable for this court to uphold," the judge said.

A December deadline was set.
