London, Jan 31 (IANS) Member of the British royal family, including Prince Harry, are using black taxis to travel to unofficial engagements instead of expensive fleet cars as the Queen is on a cost-cutting spree.

Minor royals Viscount Linley and Lady Sarah Chatto regularly book Dial-a-Cab taxis. Now financial advisers have devised plans for more senior royals to use the cabs wherever possible, including Prince Harry and Princesses Beatrice and Eugenie, reports dailymail.co.uk.

Members of the Royal household staff, meanwhile, are being encouraged to use public transport or even walk to official events or meetings instead of using cabs.

"Chelsy Davy, Viscount Linley and Lady Sarah Chatto have all used the Dial-a-Cab service and this is a cost-cutting measure. Viscount Linley is a great fan of black cabs, particularly those with the fake walnut interior, and Chelsy Davy has often called upon a cab to help her out," a source said.

"Prince Harry, Princess Beatrice and Eugenie are all being urged to use the service whenever it's deemed possible. Royal protection officers are not worried about the security implications as black cabs are viewed as an excellent way to uphold anonymity."

The Queen is well aware that cost-cutting measures need to be made, especially as her subjects are battling through lean times.
