On Tuesday night GMB, the largest union to represent ambulance staff, and Unison, which represents them, as well as porters and cleaners, announced 80,000 of its members had backed taking industrial action, but the date of the strikes is yet to be confirmed.

During Prime Minister Questions this Wednesday, Prime Minister Rishi Sunak accused Labour leader Keir Starmer of “listening to his union paymasters.”
Mr Sunak added: “If he really wants to support working people, maybe he should get off the picket line and end the strikes.”
Andrea Leadsom, the former business secretary and Conservative MP, called on both ministers and union leaders to negotiate to avert strike action before it affects millions of households.
She said: “The burden on working people from the rising cost of living is incredibly tough, but strike action that will cause misery to millions and put even more pressure on services is not the way out of this.
“The Government and unions need to work together to find a compromise that keeps services running.”
