BBC reporter Mark Daly uncovered police racism

The 2003 screening of The Secret Policeman led to 10 officers resigning and 12 more facing displicinary action.

Chief Constable Michael Todd and Deputy Chief Constable Alan Green of Greater Manchester Police met journalist Mark Daly and producer Simon Ford last week.

The documentary revealed racism at a police training college in Cheshire.

Mr Ford said: "We had a very consistent meeting with the police.

"It's rare for a programme to have the amount of impact that The Secret Policeman has had, but if we can be of use in helping the police deal with racism then that's part of the job of the BBC in building public value."

A police spokesperson said: "A range of topics were discussed in what was a positive meeting.

"Topics included developments in GMP's diversity strategy and the possibility of the BBC undertaking a follow-up programme to examine improvements which have been made since October 2003."

Reporter Mark Daly went undercover as a trainee officer and secretly filmed recruits at the Bruche National Training Centre in Warrington, Cheshire.
