Harsher Covid restrictions now apply to millions more people, as rule changes come into force across the UK.

Around six million people in east and south-east England have gone into tier four, England's highest Covid level - which includes a "stay at home" order.

Lockdowns have also started in Scotland and Northern Ireland, and measures have been reimposed in Wales after being eased for Christmas.

It comes after official UK coronavirus deaths passed 70,000 on Christmas Day.

The toughest measures - which mean the closure of all non-essential shops, as well as hairdressers, swimming pools and gyms - now apply to around 24 million people in England, more than 40% of the population.
