A three-tier lockdown is planned for England which may include the closure of pubs and a ban on all social contact outside household groups.
The Guardian claims to have seen a leaked government document.
A Government spokesman said: "We are seeing coronavirus cases rise at a rapid rate across the country and, given how serious this virus is, it is vital everyone plays their part by following the rule of six, washing their hands, practising social distancing and wearing a mask in enclosed spaces.
"As we have shown, we are prepared to take action decisively when it is necessary, and it is of course right to look how we make sure everyone understands and complies with the restrictions that will keep us all safe."
