There have been at least 691 new reported coronavirus deaths in the past 24 hours, according to the government's dashboard on Tuesday.
Some context: The recent surge comes after the UK has identified a new coronavirus variant that scientists are saying could be up to 70% more effective at spreading than others.
Large parts of England, including London and the southeast, are now under strict Tier 4 Covid-19 restrictions, and UK government health experts have suggested additional restrictions could be required to beat back this variant.
Dozens of countries across Europe, the Middle East and the Americas have also announced travel bans for the UK, or new testing and quarantine requirements for UK arrivals.
