Boris Johnson is set to introduce Plan B measure following a rapid rise of Omicron variant cases in the UK.

Reports from the Financial Times suggest the Prime Minister is planning to introduce Plan B restrictions which will include vaccine passports for larger venues and an instruction to work from home.

The move shows a growing concern about the rise in Omicron variant cases amid a Christmas party scandal relating to December 18 last year.

Reports suggest new restrictions could be announced in a press conference as early as Wednesday before the new restrictions being discussed in Parliament on Thursday.

What’s Plan B?

The Government’s autumn and winter plan suggested that some measures including the mandatory use of vaccine passports and face coverings could be required in England if cases were putting unsustainable pressure on the NHS.

Should Plan B materialise in the coming months, what would it look like?

Key restrictions to be reintroduced would be face masks, working from home and Covid vaccine passports.

The Plan B proposals draw on the findings of a review into vaccine passports earlier this year, which concluded that certification could help keep events going and businesses open.

Government plans set out how all visitors aged 18 and over to certain events could be required to be fully vaccinated.

The events listed are all nightclubs, and other venues open after 1am with alcohol, music, and dancing, and indoor events with 500 or more attendees where they are likely to stand and mix to a significant degree, or move around during the event, such as music venues or large receptions.

The plan also includes outdoor, crowded settings with 4,000 or more attendees where they are likely to stand, or move around during the event, such as festivals, and any settings with 10,000 or more people, such as large sports and music stadia.

Detailing when restrictions could be introduced in September, a government document stated: "The Government recognises this causes more disruption and has greater immediate costs to the economy and some businesses than the other Plan B interventions, so a final decision would be made based on the data at the time."

It adds: "If Plan B is implemented, the Government will bring back the legal requirement to wear face coverings in some settings.

"The precise settings will be decided at the time."

The PM's official spokesman said: "There is absolutely no plan to introduce Plan B currently. We retain that capability if required if we believe the NHS is coming under unsustainable pressure.

"We obviously keep very close watch on the latest statistics. We always knew the coming months would be challenging."
