The Prime Minister, Boris Johnson, has declared firmer restrictions for large areas of South East England with a new Tier 4 ‘Stay at Home’ alert level that will be put in law. The decision arose from the expeditious increase in infections caused by the rise of the new variant of coronavirus (COVID-19). Preliminary modelling data has established the new strain spreads considerably faster, raising the ‘R by 0.4 or more’. Tier 4 restrictions are subject to exemptions involving travelling to work or education, childcare needs and for exercising, besides that, residents in Tier 4 are told to stay at home and may only meet with one other person in an outdoor environment. All non-essential hospitality businesses must close in Tier 4, though communal worship can remain taking place. The stricter restrictions have been imposed due to the new variant having ‘significantly changed the current landscape’ and the risk of unendurable pressure placed on the NHS has called for an immediate action to safeguard the NHS and save lives. Johnson has stated that the Christmas bubble policy will no longer apply in Tier 4 due to the imminent threat the new variant poses. Tier 4 rules are due to be reviewed on 30 December 2020.
