Chancellor Philip Hammond has been speaking to BBC Breakfast about funding for the police after the wave of knife crimes.
He said his job was use to public resources in the most effective way and there were lots of demands on the spending available.
He said that police forces could be more efficient and that if they all operated at the level of the most efficient, police time would be saved that was the equivalent of 11,000 officers a year.
It was not the case that he had turned down requests for additional police funding from the Home Secretary, he said.
"Police need to ensure the prioritise the things that matter most to ordinary people," he said, adding tackling knife crime was currently the public's priority.
An extra £1bn was already being made available for the police, he said.
