WINDSOR, May, 17, 2018 (News Wires) -British armed forces carried out a carriage procession rehearsal through the ancient streets of Windsor yesterday ahead of Prince Harry's wedding on Saturday to Meghan Markle. Harry, sixth-in-line to the throne, and Markle, a star in TV drama "Suits", will tie the knot at St George's Chapel in Windsor Castle, home to the British royal family for nearly 1,000 years. After the hour-long ceremony which will be attended by Harry's grandmother, Queen Elizabeth, the couple will make a procession through the town's ancient streets on a 19th Century Ascot Landau carriage pulled by four Windsor Grey horses. The sumptuous show of British pageantry is likely to attract a huge world audience while supporters hope the union of one of the most popular royals and a glamorous American actress, a divorcee with a white father and an African-American mother, will reinvigorate the monarchy. However, much of the carefully-planned and choreographed build-up to the ceremony has been overshadowed in recent days by confusion over whether Markle's father would attend and intensive media focus on other members of her family in the run up to the wedding.
