Sir Patrick Vallance has said restrictions may need to be reintroduced as coronavirus continues to evolve.
The government has continued to ease measures across the UK since it announced the "Living with Covid" plan earlier this year. The law requiring people to stay at home if you test positive for coronavirus in England was lifted on February 24.
The government has also confirmed that lateral flow tests will no longer be free for most people in England from tomorrow. The free tests will only be available from next month to over-75s and over-12s with weakened immune systems.
