London big mistake electing a Muslim mayor, page-13

Cider,

It doesn't actually say the Mayor's Office has jurisdiction over the police force.

London mayor gains powers over the Metropolitan Police

from the above news article:

"Operational matters will still be the responsibility of the Metropolitan Police commissioner."

"The mayor will also set the annual force budget for the Metropolitan Police in consultation with the commissioner."

"But the mayor does not have the power to appoint or dismiss the commissioner, or the deputy commissioner."
