The principal and vice chancellor of Aberdeen University has apologised for any concern caused over a trip he made to a locked down part of south Wales.
Prof George Boyne said he made the trip from Scotland on Friday to see a consultant for a private health matter.
Student newspaper The Gaudie said his actions were in “stark contrast” with university rules which threaten “robust action” for those breaking Covid rules.
Prof Boyne said police had told him no action would be taken against him.
South Wales Police has been asked to comment.
Under the rules for locked down counties of Wales, nobody is able to enter or leave the area without a “reasonable excuse”.
Exemptions include to seek medical assistance.
In a statement, Prof Boyne said: “On Friday I travelled down to Wales for a private health matter, to see a consultant I have been seeing for some time.
“For the purposes of the visit I have been staying at our house in Wales which is occupied by our son.
“As I have reduced immunity, it felt like the safest option to be in our house, rather than in a hotel.
“It has been suggested to me that this may be not be in line with local guidance.”
He added: “I sincerely apologise for any concern this may cause.”
He said he had informed the senior governor of the University of Aberdeen.
Esther Robertson, senior governor at the university, said she would consult with fellow trustees to consider the full implications of Prof Boyne’s actions.
A spokesperson for the University of Aberdeen said Prof Boyne’s wife had travelled with him and that he had not yet had the appointment.
Before taking the role in Aberdeen, Prof Boyne had been pro vice chancellor and head of the College of Arts, Humanities and Social Sciences at Cardiff University since 2012.
