The Queen’s taxpayer-funded costs rose by 13 per cent in the past year, new accounts show.
Public funds used by the Queen for official expenditure and duties went up from £41.9 million to £47.4 million.
More than £4 million was spent on the initial phase of improvements at the palace, including the removal of old wiring, while £21.4 million went on payroll costs.
The Sovereign Grant accounts also show an increase in travel costs, from £4.5 million to £4.7 million.
The most expensive trip was Prince Charles’s tour of India and the Far East in November 2017, which cost £362,149.
Over the year, the prince used the Royal Train – at a cost of about £20,000 a trip – twice as often as the Queen.
The Prince of Wales and Duchess of Cornwall carried out 619 UK engagements last year. The Queen undertook 154 official engagements, down from 162 the previous year.
