Pregnant Duchess of Cambridge says she's 'much better' as she leaves hospital after three-night stay The Duchess's immediate engagements have been cancelled, though the Duke is expected to honour two engagements this weekend, which include a visit to the Albert Hall on Saturday night and a military tournament at Earl's Court on Sunday. Royal aides said it was too early to say when the Duchess would be well enough to resume her public duties, though it seems likely she will allowed to rest for the remainder of the month, meaning she may not appear again in public until the Royal family attend church at Sandringham on Christmas Day. Meanwhile the Australian broadcasting regulator has received complaints about a prank call made to the hospital by two presenters from the Sydney radio station 2Day FM. Mel Greig and Michael Christian managed to discuss the Duchess's condition with a nurse by pretending to be the Queen and the Prince of Wales. Despite apologising for the hoax, Mr Christian seemed unrepentant as he took to the airwaves today, describing the prank as "just a big fat joke."
