We are currently expecting to provide all services as usual on Monday, and all patients should attend for appointments as planned, unless we have been in touch directly to reschedule.
“Whilst we will do everything possible to minimise disruption, there may be some delays on Monday and we apologise to any patient whose appointment is affected.”
Meanwhile North West Ambulance Service director of emergency Services, Derek Cartwright said: “Our discussions with the unions on the subject of exemptions are still ongoing and there is still the possibility that things could change.
