Blackpool Tower joined some of the country’s most famous landmarks, turning pink in honour of the second child of the Duke and Duchess of Cambridge.
It follows the decision to turn The Tower blue when Prince George, the couple’s eldest child, was born in 2013.
The Duchess gave birth to a daughter, weighing 8lbs 3oz, at 8.34am on Saturday – and The Tower followed landmarks including the London Eye and Tower Bridge, turning pink on Saturday night to mark the arrival .
The princess is now fourth in line to the throne, after her big brother.
Proud father William spoke of his joy following the birth, telling the waiting press he was “very happy”.
A name for the princess has yet to be announced but both Charlotte and Alice are popular with the bookies, while a flurry of bets at the weekend saw the odds slashed on her being called Olivia.
A statement from Kensington Palace following the birth read: “Her Royal Highness The Duchess of Cambridge was safely delivered of a daughter at 8.34am.
“The baby weighs 8lbs 3oz.
“The Duke of Cambridge was present for the birth.
“The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall, Prince Harry and members of both families have been informed and are delighted with the news.
