The Royal line of succession is about to shift. The Duchess of Cambridge is in labour.

Kate Middleton was driven to hospital early this morning along with her husband, Prince William. There had been speculation that the baby might not be born in London. But Kate is now in the hands of medical teams at St. Mary’s hospital, where William and his brother Harry were born.

Experts say, since this is her first pregnancy, it could be several hours before Kate gives birth. When she does, the news will be rushed to Buckingham Palace and posted on a notice board. Crowds are already gathering outside the palace to await the officially word.

Meanwhile, news of the imminent arrival has ignited a flurry of betting about what the royal infant will be named. The online bookie Ladbrokes took 50,000 bets in the hours after the news broke. The favourites are “Alexandra” if it’s a girl and “James” if it’s a boy.

It may be awhile before the name is known. It is not uncommon for the palace to take its time to choose just the right name.
