The Queen is in line for a 6.5% payrise and could net a cool £45.6 million from the taxpayer next year if the way she is funded stays the same.

Figures released show a total profit of £304.1 million for the Crown Estate. If the Queen receives her Sovereign Grant calculated at the customary 15% of that she would be handed £45.6 million from the Treasury in April 2017, an increase of £2.8 million up from £42.8 million this year.

Prince Charles also revealed that his income from the Duchy of Cornwall estate rose to more than £20 million for the first time to £20.467 million up from £19.845 million the previous year. Expenditure on the area of his accounts that funds Prince William, Kate and Harry was also up 9.5% from £2.965 million to £3.249 million, although officials would not say how much of the increase was down to the three young royals or itemise how that money was spent.

The bill for royal travel was down to £4 million from £5.1 million the previous year, but there were still some eye-watering travel costs billed to the taxpayer including a £94,409 charter plane for Prince Charles and Camilla's tour of the Balkans in March. Charles and Harry also spent £74,500 on a charter flight to commemorate the centenary of the Gallipoli campaign last April. Charter flights for The Queen and Philip to travel to Malta in November 2015 for the Commonwealth Heads of Government Meeting cost £55,358 with an additional £8,696 on scheduled flights for their staff, and Prince Harry's flights to Nepal in March cost the taxpayer £33,278.

Some 221 helicopter journeys were taken at a total cost of £569,483.

The Royal Train also racked up some hefty bills including £20,034 for The Queen and Philip to travel from London to Aberdeen last August and £33,249 for Prince Charles to travel to travel from Ayr to Yorkshire to Aberdeen in September.

The largest expense was £16.3 million spent on repairing crumbling palaces.
