Boris Johnson has refused to say if he would mount a legal challenge to a second Scottish independence referendum, if Nicola Sturgeon does press ahead with another ballot without the agreement of UK ministers.

Instead, the British Prime Minister highlighted the AstraZeneca coronavirus vaccine as being a prime example of the “strengths and advantages” of the United Kingdom.
