They say he is self-isolating at home.

"As required, he has begun self-isolating at home for the mandatory period. We are grateful to know that he is double vaccinated and will be monitored by a very capable team.

"During this period of self-isolation, members of the media are kindly requested to respect our space. Please rest assured that we will keep you informed of his return to work.
