As it happened: Tighter rules for Christmas outlined amid surge in cases - BBC News
The relaxation of Christmas rules is scrapped for much of south-east England and cut to just Christmas Day for the rest of England, Wales and Scotland.
We can bring you some business reaction to Boris Johnson's announcement of tier four restrictions in the south and east of England, including London.

"The consequences of this decision will be severe," Helen Dickinson, chief executive of the British Retail Consortium said.

She said the government’s "stop-start approach" to coronavirus restrictions has been "deeply unhelpful" for retailers ahead of the usually busy and lucrative Christmas period.

Adam Marshall of the British Chambers of Commerce echoed Dickinson, calling on the government to "address the economic consequences of its actions".

He said that retailers needed extra financial support to get through the winter and beyond.

Federation of Small Businesses vice-chair Martin McTague said tier four restrictions would be a "hammer blow" to non-essential retailers.

"From shops to hairdressers, this would normally the one of the busiest times of the year," he said.

"Many will have bought extra stock and increased staff hours, now their takings are to disappear literally overnight."

Michael Kill, chief executive of the Night Time Industries Association, said retailers had "lost all confidence" in the UK government's strategy for tackling coronavirus.

"The unrelenting closing and reopening of businesses is costing owners hundreds of thousands of pounds, and coupled with the erratic decision-making around restrictions, is rapidly destroying the ability of the sector to bounce back," he said.
