MPs have voted in favour of reintroducing some Covid restrictions as part of the prime minister's back-up plan to limit the spread of Omicron, despite a large Tory rebellion.

The "plan B" measures include the return of mandatory face coverings to most indoor venues, the introduction of Covid passes to large venues and mandatory vaccinations for NHS workers.

The Conservative MP for Maldon, John Whittingdale, voted in favour of all the measures following the House of Commons debate last night (Wednesday, 14 December).

Many of his fellow Conservative MPs, however, opposed the measures - marking the largest rebellion under Boris Johnson's leadership.

Tory rebels most strongly opposed the introduction of Covid passes, with 97 voting against the measure.

61 Conservatives voted against mandatory vaccinations for NHS workers, while 38 voted against the extension rules regarding face coverings, which are now compulsory in most indoor venues.

Covid passes will be checked from 6am today (Wednesday, 15 December).

You can get a pass if you have received two doses of an approved vaccine, or one of the single-dose Janssen vaccine, you have had a negative PCR or rapid lateral flow test within the last 48 hours or you have a medical exemption.

It is simple to get a digital Covid pass through the NHS app on a smartphone or tablet or via the NHS Covid Pass website, where it can be downloaded and printed.

If you cannot apply digitally, you can get an NHS Covid Pass letter sent to you by post.

Mandatory vaccinations for NHS staff will come into force from April 1 next year.
