It's a girl, but the guessing game over the Princess of Cambridge continues as the public await the announcement of the name chosen for the youngest royal, born on Saturday.

As the first official photograph of the Duke and Duchess of Cambridge's daughter dominated newspaper front pages, the names Alice, Charlotte and late frontrunner Olivia were among the bookmakers' favourites. Though there was speculation that there could be an announcement on Sunday, the couple kept punters in suspense.

After her first official photocall, sleeping soundly in her mother's arms on the steps of the private Lindo wing at St Mary's hospital, Paddington, the young princess – the first in 25 years and fourth in line to the throne – was taken to the family's London home at Kensington palace. The Cambridges will stay briefly in London before returning to Anmer Hall, their country home on the Queen's Sandringham estate in Norfolk, in the next day or two.
