PRIME Minister David Cameron has joined in the fight for justice after the deaths of four East Lancashire people murdered in Pakistan. He confirmed he was taking a personal interest in the cases of the Yousaf family , three members of whom were shot dead in 2010, and grandmother Fukraz Begum, beaten to death with a blunt instrument earlier this year. Mr Cameron promised to meet their MP Andrew Stephenson when Parliament reassembles in Autumn to update him on progress after the foreign and commonwealth office stepped up pressure on the Pakistani authorities over the summer. Mr Stephenson raised the cases with the Prime Minister after repeated efforts to get action through meeting ministers, parliamentary questions and a special debate in the House of Commons.
