On December 15, the British government announced the emergence of a variant "new crown" virus, and speculated that the intensification of the epidemic may be related to the variant virus. At the same time, the epidemic in London and other places was raised to the third level, which is the "extremely high" alert level. All non-essential businesses in places such as London and Essex, such as bars, restaurants, and cafes, as well as hospitality business premises, such as hotels and homestays, must be closed again.
