Reaction to undercover police inquiry

Key Points

• Theresa May has announced a judge-led inquiry into the way the Metropolitan Police's undercover police officers operated during the investigation into Stephen Lawrence's murder
• A review of the case - by the barrister Mark Ellison - found there were reasonable grounds to suspect that at least one detective on the team was corrupt
• 18-year-old Stephen was stabbed to death by a group of up to six in an unprovoked racist attack as he waited at a bus stop in Eltham, south-east London, on April 22 1993
• It took more than 18 years to bring two of his killers - Gary Dobson and David Norris - to justice
• Mrs May has also said she wants a new offence of "police corruption"
