White male recruits to the Metropolitan Police are having to wait up to three years to join as ethnic minority and women applicants are being prioritised.
The recruits are among 10,500 - taken on by the UK's largest force between 2001 and 2003 - who are being sent for training in staggered intakes.
But the Met has tried to make each intake balanced, moving some women and ethnic minority recruits up the queue.
A spokesman said a more diverse force would deal with the community better.
But of course the same doesn't apply to the NHS.
