Excerpt:
Britain's most senior Muslim police officer, who leads the Metropolitan police community outreach programme, is stepping down, sparking complaints by colleagues that he should have been promoted.
The news that Commander Mak Chishty had resigned prompted a senior anti-terrorism official to say: "He should have been promoted to deputy assistant commissioner a long time ago."
Police insiders who have worked with Chishty, 49, said he was "seriously underestimated".
After 31 years' service he is eligible for retirement, but his departure in June will bring into question Scotland Yard's strategy on relations with British Muslims.
