The North's policing board meets later today amidst what it says is a crisis created by London's demand for £17m in savings.
Board members say if the cuts are pushed through, it will inevitably mean job losses and reduced front-line services.
At noon today the board meets with a long agenda but top of it will be London's decision to cut £17m off the PSNI's budget.
The power-sharing executive had been looking for more money from London to pave the way for the devolution of policing.
The Northern Ireland Office has denied the proposed cuts are an ultimatum but at the same time says that it will put in a business performance review team if they are not agreed.
This comes at a time when the dissident threat is high and a recent internal review said the police are not delivering what the public wants.
