Meghan Markle fans were left distraught when her character Rachel Zane left “Suits” in the Season 7 finale, which aired in the US on Wednesday night. It marks the final ever acting appearance for Markle, 36, who will become a full-time royal when she ties the knot with Prince Harry, 33, at Windsor Castle next month. In 2011, Harry was Prince William’s best man at William’s glittering wedding to Kate Middleton. He has invited his sibling to repay the favour when he marries Markle. The couple has invited 600 guests to their wedding and a lunchtime reception afterwards at Windsor, with another 200 attending a private evening event at nearby Frogmore House.
