LONDON (AP) — A law intended to prevent police and other officials from covering up errors and wrongdoing is set to be approved by British lawmakers on Tuesday, 37 years after the country’s deadliest sports tragedy sparked a campaign for justice.The Public Office (Accountability) Bill imposes a legal duty of candor on public officials to tell the truth about public tragedies whatever the impact on their reputation.The legislation is more commonly known as the Hillsborough Law, after the 1989 disaster in which 97 Liverpool soccer fans were killed in a crush at Hillsborough Stadium in Sheffield. An independent inquiry in 2012 found police had covered up their own mistakes and blamed the deaths on unruly supporters. The bill is due to complete passage through the House of Commons on Tuesday after a delay caused by wrangling over whether it would apply to Britain’s spies. After pressure from bereaved families, the government has agreed that intelligence services will be covered by the duty of candor, but with a “secure process” for disclosing information if it could affect national security.The bill will become law after being approved by the House of Lords, Parliament’s upper chamber.
