Conservative and Liberal Democrat councillors in Calderdale are set to unite against the ruling Labour group to overturn the forthcoming budget.
The coalition has produced an alternative budget which includes measures to reverse recent changes to car parking in Calderdale, employ more street sweepers and bring in restrictions to sick pay for council staff.
The amendments are to be put forward at the annual budget meeting on February 24 at Halifax
Town Hall - and could go through as a Conservative and Liberal Democrat coalition will wield a majority vote over Labour.
It could spell great upheaval in the political make-up of Calderdale Council with the power shifting from the Labour group which has 21 councillors compared to the comined 28 of a Tory/Lib Dem alliance.
