Mark Drakeford will lead a press briefing today following a 21-day review of lockdown rules.
The First Minister will update the nation during the regular review of the coronavirus regulations, which happens every three weeks.
The Welsh Government is not expected to make major changes to Wales' coronavirus rules.
However, it's thought Mark Drakeford will announce changes to measures for single parents and those living on their own in areas with local restrictions.
