The First Minister of Wales, Mark Drakeford will today confirm changes to the rules on meeting people indoors to help prevent the spread of coronavirus in Wales.
The changes come as parts of Wales have seen an increase in cases of the virus linked to people meeting and socialising with others indoors but without social distancing.
From Monday, a new limit of six people will be introduced on the number of people who can meet indoors at any one time. All six must belong to the same extended household group.
In addition, facemasks in shops and other indoor public spaces are to be made compulsory in Wales from Monday.
First Minister Mark Drakeford said the change came as a threshold of 20 people in 100,000 now had Covid-19 in Wales.
The rule will not apply to children aged 11 and under, and up to 30 people from different households will still be able to meet outside.
There will be no change to the current rules, which allow up to four households to form an exclusive extended household in Wales, and no change to the rules on meeting outdoors.
These changes will not apply in Caerphilly County Borough Council area, where local restrictions have been introduced, including a suspension on extended households meeting indoors, to control a sharp rise in coronavirus cases and protect public health.
