Scotland will go into a new lockdown with people ordered to stay at home for the rest of January to tackle the escalating COVID-19 crisis.
First Minister Nicola Sturgeon told the Scottish parliament that from midnight on Monday people would face a legal requirement to stay at home except for essential purposes.
