Tourists in London will splurged over £50 million more than normal during the four-day weekend, with hundreds of thousands of extra guests in town for the Royal Wedding.

With the celebrations completed yesterday, many travellers to the UK capital will begin the important task of spending money.

“We anticipate that 500,000 additional shoppers will give retailers a £50 million royal wedding boost,” said Jace Tyrrell, of the New West End Company.

The organisation represents over 600 retailers in London’s Bond Street, Oxford Street and Regent Street.

The impact of the Royal Wedding is also expected to continue for many days, with the “halo honeymoon effect” sweeping across the capital.

Simon Burdess, trading director of Fortnum & Mason, told the Associated Press: “We are very excited about the royal wedding. Sales of commemorative products, including our own range of china and food items, have exceeded expectation in the run-up to the big day.”

Michelle Dowdall, spokeswoman for Debenhams, said: “Royal wedding memorabilia has been flying out of stores in recent weeks, with many lines selling out already in our Oxford Street flagship store.

“As visitors and tourists descend on London, there will no doubt still be huge demand for these items over the weekend.”
