The prime minister is to make a statement to MPs on Monday giving details of new restrictions to slow the spread of coronavirus in England.

A letter from Boris Johnson’s chief strategic adviser to MPs in the north-west of England seen by the BBC states “it is very likely that certain local areas will face further restrictions”.

A three-tier system will see areas face differing rules based on case severity.

It comes as the chancellor announced support for UK firms ordered to close.

Under the new restrictions, pubs and restaurants could be closed in parts of northern England and the Midlands – where some of the highest number of cases are occurring – while a ban on overnight stays is also being considered.

It is understood that the most severe measures will be agreed with local leaders in advance before they are implemented.

The letter to the MPs from Downing Street adviser Sir Edward Lister says the government was hoping to “finalise these details as soon as possible” amid “rising incidence in parts of the country”.

It also cites the “engagement that is taking place today and during the course of the weekend with local authority leaders in your region”.

Sir Edward says the set of measures being discussed “present difficult choices. We must seek to strike the right balance between driving down transmission, and safeguarding our economy and society from the worst impact”.
