William and Kate currently hold the title of Duke and Duchess of Cambridge, following the Dukedom gifted to Prince William as a wedding gift in 2011.
'The royal couple’s child will officially be known as His or Her Royal Highness the Prince or Princess of Cambridge'
In a statement released yesterday, a palace spokesman confirmed:
'The royal couple’s child will officially be known as His or Her Royal Highness the Prince or Princess of Cambridge.'
This corresponds to the Queen's announcement on 31 December 2012, stating:
'All children of the eldest son of The Prince of Wales should have the style, title and attribute of Royal Highness with the titular dignity of Prince or Princess prefixed to their Christian names.'
The baby, whose sex is not publicly known, is reportedly due on Saturday 13 July and will be born at St Mary's Hospital in Paddington, where William was born in 1982.
In a statement, St James Palace said: ‘Cambridge and Strathern have had Royal connections since the fourteenth century in the peerages of England and Scotland and were both available.
‘Prince William is descended from the son of George III who was created Duke of Cambridge in 1801 through Queen Mary.’
The Mayor of Cambridge, Councillor Paul Saunders, released a statement following the news, stating:
'It is a great honour and I'm sure the people of Cambridge will appreciate it greatly.'
'I think it's lovely to continue the close link with the Royal family. I think anything which helps to keep Cambridge in the public eye is a good thing as we rely on tourism.'
The queen can choose any title she wishes, though the title may not currently be in use.
