The Royal Collection Trust's net income has fallen by more than £10 million with visitor numbers to royal attractions and retail sales also down, accounts have shown. "Looking ahead, challenges in the domestic economy and global forces affecting international travel will put pressure on visitor numbers and retail income. "There is still public appetite to visit Royal Collection Trust sites and exhibitions. In London, a reduction in visitor numbers was anticipated. "By contrast, visitor numbers at the Palace of Holyroodhouse increased as a result of additional operating days and an expanded programme of group tours."
