A pub named after the Duchess of Cambridge will celebrate the royal baby's birth with a new ale named Heir Raiser.
Punters will be treated to an English tea party after the news is announced and managers have prepared decorative banners to mark the occasion.
Bar staff were pulling pints of Heir Raiser at the pub in Windsor, Berkshire, this afternoon (Monday) as the world waited for news of the latest addition to the Royal Family.
The pub has also launched a sweepstake and will give a bottle of champagne to the person who manages to guess the date and time of the birth most accurately.
Daniell Park, manager of the Duchess of Cambridge, said: "The day after the baby is born, we are going to be throwing a party with tea and cakes.
"We have got some banners ready to go up when we find out whether it's a boy or a girl.
"We have also got our special McMullen's beer which is already proving to be very popular."
