Matt Hancock has backed police in being more stringent in enforcing the lockdown rules.
The Health secretary told Sky News’ Sophy Ridge on Sunday programme: “I’m absolutely going to back the police because the challenge here is that every flex can be fatal.
“You might look at the rules and think ‘Well, it doesn’t matter too much if I just do this or do that’.
“But these rules are not there as boundaries to be pushed, they are the limit to what people should be doing.
“The police are right to take very seriously the rules we have brought in. We haven’t brought them in because we wanted to, we’ve brought them in because we had to.
“Every flexibility can be fatal.”

There have also been increasing calls for teachers to be prioritised to receive the Covid-19 vaccine, to help speed up the re-opening of schools.
A member of the government’s Joint Committee on Vaccination and Immunisation (JCVI) member Professor Adam Finn said they would be discussing the role of teachers during committee meetings this week.
The professor of paediatrics at the University of Bristol said: “I can’t predict exactly what will be prioritised but I can say that we will be discussing this and coming up with a plan, and I can also say that when it comes to teachers I think we all appreciate the critical role that they all play and so that really will figure in the discussions.”
