The Royal Armouries was forced to pay out more than £1m in redundancy costs in 2010-11, making 56 employees redundant at an average cost of almost £18,000 a head.

The costs of the redundancies were more than a quarter of the museum’s salary costs for the year, and about an eighth of its grant-in-aid.

A spokeswoman for the museum said: “We had to make all of the redundancies in year one due to the cuts imposed by the government. Most of the redundancies were voluntary.”

Among the redundancies were the Leeds museum’s education team, as well as its horse riders, actors and stable staff.

The museum is currently implementing a review to reduce spending by £3.4m over four years.
