(BBC) A grieving father whose son died in Iraq said he would walk to London from north Wales just to tell US president George Bush what he thinks of his war effort. During his visit to the UK, Bush wants to offer his prayers and tell the bereaved families their loved ones did not die in vain. (...) But Reg Keys, who lost his 20-year-old son Tom in June 2002, said he holds Bush and Tony Blair responsible for his death. "I don't know how the man (Bush) has the nerve to show his face in his country after costing the lives of 53 British servicemen," said Mr Keys, of Llanuwchllyn, near Bala. Tom Keys died days before his 21st birthday. He was one of six military policemen shot dead in Al Majar al-Kabir last June. The servicemen were chased into a police station and shot. (...) Mr Keys said: "I haven't had an invitation for an interview with Mr Bush, if I did I would literally walk from Wales to London to meet the man, look him in the eye and tell what I think of him."
