The Metropolitan Police incurred extra costs of at least £10 million in dealing with the terrorist attack on London Bridge and Borough Market in June, according to a new London Assembly report.
According to the London Assembly budget & performance committee's report Who's paying the Bill? – published on Tuesday – the cost of policing in the aftermath of the 3 June attack on London Bridge has reached eight figures.
"The Met deployed 600 counter terror officers on the streets of London for seven days straight after the London Bridge attack and has 260 officers working at Grenfell," says the report.
"The Met informed committee officials that the London Bridge attack alone will cost the Met over £10 million in extra resources, although this figure has not been publicly confirmed.
"The Home Office's current guidance expects the Met to hold contingencies for unexpected incidents such as London Bridge or Grenfell. We think that this is an unreasonable position and call on the Home Office to change the special grant guidance."
In the report the cross-party committee of Assembly members urges the Mayor to lobby central Government to change the rules.
Eight people died as a result of the attack on the night of Saturday 3 June, and Borough Market remains closed for 10 days whilst police investigated the incident.
