Members of Brighton and Hove City Council have failed to set a budget after six hours of negotiations, and will now reconvene on Tuesday 3 March.
At just after 10.30pm the council chief executive Penny Thompson said it was unlikely they were going to be unable to reach an agreement this evening.
They were trying to decide whether tax payers in the city will face the biggest increase in their bills in the country.
The Greens want a rise of almost 6%, which would equate to more than £70 a year for an average household.
They say without a big rise they will have to make drastic cuts in public services. Both Labour and the Conservatives feel this is too high.
The opposition Labour group leader Warren Morgan tonight argued for a 2% rise in council tax.
