Wales will go into a firebreak lockdown over Christmas.
The nation will move into alert Level 4 as case numbers rise and the number of those bring treated in hospital for Covid increase.
Under the measures non-essential retail will close from the end of trading on Christmas Eve as well as leisure facilities and close contact services.
It will mean no Boxing Day sales for retailers.
All hospitality will close from 6pm on Christmas Day and everyone will be urged to work from home where possible from today.
From December 28 the whole of Wales will go to Level 4 restrictions.
These are the Level 4 restrictions
This will also include restrictions on holiday accommodation and travel.
First Minister Mark Drakeford said while these measures were to be imposed nationally this could be reviewed after three weeks.
He said if "parts of Wales had established themselves as being in a different position in a reliable and sustainable way" the Government will see whether it was "sensible" to introduce some regional differentiation.
Business and political leaders in North Wales have called for parts of the region to be placed in a lower tier due to the lower Covid rates.
Extra financial support will be provided to businesses impacted.
Welsh Government also now advise a bubble of two households rather than three over Christmas.
Sara Jones, head of policy and external affairs at the Welsh Retail Consortium, said that while they fully support the Welsh Government’s efforts to get on top of the public health situation and to bring down the transmission rate lockdowns cost Welsh retailers more than £100m a week in lost sales.
“Whilst we do not underestimate the enormity of the challenges facing decision makers right now, Welsh retailers have taken every mitigation possible to keep customers and staff safe," Ms Jones said.
"Government advice clearly highlights the minimal impact shop closures will have on the public health objectives, indeed it explicitly recognises the socio-economic harms of the closure of certain sectors in terms of weekly GVA impact which would be equivalent to at least 300 10-year lives”.
"Lockdowns cost Welsh retailers over £100m a week in lost sales, and with continued low footfall in towns and city centres, many retailers face the stark reality of further job losses and store closures as a result of mounting rent bills and a return to full business rates liability from April.
"This forced closure will also make it more difficult for some shops to sell unsold pre-Christmas stock. Whilst we welcome the promise of support for those businesses affected, and that click and collect is permitted to stay open, the blunt reality is the offer of grant support won’t make up for those lost sales – we can only hope those shops forced to close can weather the storm ahead."
