By Belinda Goldsmith LONDON (Reuters) - British Prime Minister David Cameron announced on Thursday an independent inquiry into letters of immunity sent to IRA suspects after an angry response to the freeing of an Irishman accused of a 1982 bombing that killed four soldiers in London. Cameron said an independent judge with full access to government files and officials would lead the review and report back by the end of May. Northern Ireland's most senior politician, First Minister Peter Robinson, had threatened to resign unless there was a full inquiry into the guarantees, saying they were a "deliberate attempt to circumvent the courts". Cameron said it was clear that there had been a "dreadful mistake" in the case of John Downey, who walked free from a London court this month because of an immunity letter. Downey, 62, from County Donegal in Ireland, was charged with murdering four members of the Royal Household Cavalry who were killed 32 years ago when a car bomb exploded in Hyde Park as they paraded towards Buckingham Palace on July 20.
