Maintaining David Cameron's Downing Street garden has been costing the taxpayer nearly £50,000 a year.
The picturesque half-acre plot behind the Prime Minister's residence is one of the perks of the job.
After the Camerons moved in three years ago they installed a children's play area.
The Cabinet Office disclosed details of spending on the garden in response to parliamentary questions from Labour frontbencher Diane Abbott.
The bill for 2010-11 came to £49,060, and the following year it was £47,321.
However, Cabinet Office Minister Francis Maude stressed that spending in 2009-10 under Gordon Brown was even higher at £56,027.
Ms Abbott said: "Is there no way these costs could be cut a bit?
"David Cameron's bedroom tax is hammering families - including armed forces families, disabled people and foster carers - who are already struggling to make ends meet, whilst money is being lavished on David Cameron's garden."
