Responding to a tweet from Kevin Schofield, editor at PoliticsHome, which said Johnson's move was a "U-turn". the SNP Westminster leader said: "I think you know that this is a Prime Minister who makes it up as he goes along. Yesterday is s different country. Here is today’s menu."

Meanwhile, the UK's approach to developing "herd immunity" against Covid-19 has been called into question by the World Health Organisation (WHO).

Spokeswoman Margaret Harris said not enough is known about the science of the coronavirus, and that while "theories" can be talked about, the current situation requires "action".

On Friday, the UK's chief scientific adviser Sir Patrick Vallance said it is hoped the Government's approach to tackling coronavirus will create a "herd immunity" to the disease.
