Ahead of the Christmas weekend, Ms Sturgeon had appealed to Scots to follow recommended advice, rather than legal restrictions.
She told Scottish Parliament a week before Christmas Eve: “Before and immediately after Christmas, please minimise your social mixing with other households as much as you can.
“However, if you do plan on socialising – either at home or in indoor public places – we are asking that you limit the number of households represented in your group to a maximum of three. And make sure you test before you go.”
Wales and Northern Ireland also brought in renewed restrictions after Christmas Day, with Welsh First Minister Mark Drakeford announcing that, as of Boxing Day, nightclubs will be shut and the rule of six reinstated.
