NHS England said 111 services are still available and there is “very little disruption for now”, with “tried and tested contingency plans”.

Northern Ireland’s Department of Health is also working to minimize disruption and steps have been taken to avoid the risk of other critical systems and services being affected.

Chief executive Simon Short added: “We continue to work with the NHS and our health and care agencies as well as our technology and security partners, with a focus on getting it all back on track. systems over the weekend and early next week.”
