The Scottish Government has been urged to explain whether it plans to return to regional variations after imposing lockdown across most of Scotland.
Scottish Conservative leader Douglas Ross says the decision to place all of mainland Scotland into Level 4 must be fully understood.
On Saturday evening, the First Minister said Level 4 restrictions would apply for three weeks, starting at a minute past midnight on Boxing Day morning.
She said the decision will be reviewed after two weeks (on 9 January) but would be in place for at least three weeks (until 16 January).
Both of these dates are Saturdays. Coronavirus restrictions have rarely been altered over weekends.
Scottish Conservative leader Douglas Ross said: “Since the beginning of November, Scotland’s 32 local authorities have adapted to the Scottish Government’s system of levels.
“People have made immense sacrifices, as they have done since March, in order to prevent the spread of Covid-19.
“For the government to abandon its system may be justifiable due to the continued spread of the virus and the unknown nature of this new strain. However, it is crucial that people are told exactly when these blanket restrictions are going to be reviewed.
“We all understand how volatile the situation is, but people are entitled to know whether there will be a return to the regional system of levels when it is safe to do so or whether this blanket approach may become the new normal."
