asked the Secretary of State for Defence what is the annual revenue cost of running the Royal yacht "Britannia"; and what is the complement in total and the weekly salaries attributed to it.
The running cost of the Royal yacht "Britannia" for the financial year 1979–80 is estimated to be some £2 million. This figure excludes the cost of her current refit. The complement when on royal duty is 276 and the average weekly salary bill is some £33,000. The complement and salary bills are reduced when she is in refit.
