The most comprehensive review of race relations in decades was promised by the Prime Minister yesterday after a report found institutional racism in the police and other public bodies. Tony Blair said the report would force Britons to confront racism in society. He promised new legislation to outlaw discrimination. 'It will certainly lead to new laws and - more importantly than that - it should lead to new attitudes that extend well beyond the police force and bring about changes to the nation as a whole,' Mr Blair said. The report followed an inquiry into a police probe of the murder of black teenager Stephen Lawrence, who was stabbed to death in 1993. Five white youths were arrested, but three were acquitted by a court and two never got as far as a trial following what the inquiry found to be incompetence, racism and a fundamental lack of leadership in London's police force. There have been widespread calls for the resignation of the Commissioner of the Metropolitan Police, Sir Paul Condon, for failing to acknowledge institutional racism exists in his force. Home Secretary Jack Straw yesterday backed the commissioner but promised a review of the force and new disciplinary codes to tackle racism within the ranks. Further government measures will include the setting of targets for the recruitment of members of the country's black and Asian communities into the police.
