Derby City Council leader Chris Poulter has called for people to "work our hardest to do the right thing for Derby and stay home except for essential reasons".
He said: "While none of us would wish for further restrictions, these latest measures are unfortunately necessary for us to regain control over the virus."

Mr Poulter added he hoped the nationwide vaccination programme and imminent roll-out of community testing "will help Derby to reduce transmission and move away from severe restrictions as soon as it is safe to do so".
"In the meantime, do remember that there is always help and support available for those who need it in Derby through our support grants and Derby’s Community Hub," he said.
