Brent, Harrow and Barnet Met Police commands may be merged as £800m to £1.4 billion of budget cuts over the next four years eat into the number of available police officers.
The Met revealed is considering merging the three borough commands down from three into one.
Brent is under the command of Michael Gallagher while Barnet and Harrow are under the command of Adrian Usher and Simon Ovens.
Met Commissioner Sir Bernard Hogan-Howe believes the budget cuts will lead to the loss of 5,000- 8,000 police service jobs.
A Met Police spokesman said; “The Metropolitan Police Service is undergoing a significant transformational change programme.
“As part of this we are looking at many options for change, one of which is implementing a model which will see a number of boroughs sharing services and resources.
“Further work is being done to explore how we could manage services like neighbourhood policing , response, investigation and protection of vulnerable people across a number of boroughs.
“No decisions will be made until the Met’s budget position is clear. This will not be until the New Year, once the Comprehensive Spending Review is announced and our grant allocation is confirmed.”
Labour London Assembly Member for Brent and Harrow, Navin Shah, has branded the potential move as ‘ridiculous’
London Mayor Boris Johnson said in 2012 every Borough needs a “single figure at the top… the borough commander.”
Since May 2010 Brent has lost 227 uniformed officers and 111 PCSOs.
