Boris Johnson has said there will not be any further Covid restrictions before Christmas Day, but has warned tougher restrictions could be implemented afterward. 

In a video message released on Twitter, Mr Johnson said there is "continuing uncertainty" around the Omicron variant and more restrictions cannot be ruled out after December 25.

There is not enough evidence to justify stricter measures, but the situation remains “finely balanced” and people should “exercise caution”. 

In the video message, the Prime Minister said: “There is no doubt that Omicron continues to surge with a speed unlike anything we’ve seen before.

“The situation remains extremely difficult but I also recognise that people have been waiting to hear whether their Christmas plans are going to be affected.

“So what I can say tonight is that naturally we can’t rule out any further measures after Christmas – and we’re going to keep a constant eye on the data, and we’ll do whatever it takes to protect public health.

“But in view of the continuing uncertainty about several things – the severity of Omicron, uncertainty about the hospitalisation rate or the impact of the vaccine rollout or the boosters, we don’t think today that there is enough evidence to justify any tougher measures before Christmas.

“We continue to monitor Omicron very closely and if the situation deteriorates we will be ready to take action if needed.

“What this means is that people can go ahead with their Christmas plans but the situation remains finely balanced and I would urge everyone to exercise caution, to keep protecting yourselves and your loved ones, especially the vulnerable.

“And remember to keep following the guidance – wear a mask indoors when required to do so, keep fresh air circulating, and take a test before you visit elderly or vulnerable relatives.”

He said people should “drop everything” if they need to get a vaccine.
