Mayor Sadiq Khan has told the London Assembly they should campaign with him against cuts to the funding of the Metropolitan Police.
During discussions on his draft budget, he warned Assembly members that the Met faces financial trouble after cuts from central government.
Khan decided to raise council tax to provide an additional £24.2m for the police, a decision he described as “difficult”.
“I am determined to deliver real results for Londoners, and this means maintaining the strategic target of 32,000 police officers in order to keep the capital safe,” he said.
“In the face of continued pressures on the police budget this is becoming increasingly difficult.
“This year, I have done everything I can to protect police officer numbers – including making the very difficult decision to raise council tax.
“But if the Government subjects London’s police service to any further cuts, it will become harder than ever to maintain the number of police on our streets,” he added.
He has also asked London MPs and borough leaders to join his campaign.
