David Lammy will be seething. His ideas for compulsory civic service were promoted in the pages of Prospect a year ago. He has been lobbying within the Labour Party for the policy for considerably longer.
Unfortunately, like so many other good ideas proposed during the Brown era, this one just got stuck in the system and Cameron simply nicked it from under the Prime Minister's nose.
Labour supporters should be very worried about this. It is a sign of a properly-functioning opposition that it can move more quickly than a lumbering decadent government.
