The Duchess's rumoured due date of 25 April has passed and speculation is mounting that she is overdue, although on a previous occasion she said the baby was expected in mid to late April.

Prince Harry may not be able to meet his new niece or nephew until mid-May unless he or she is born before he flies to Australia later today.

He is meeting Australian Army units in Perth and Sydney before he embarks on an official tour of New Zealand until 16 May.

Ladbrokes said William and Kate's fourth wedding anniversary on 29 April is now one of the bookmakers' favourite arrival dates at 4/1.

Alice remains the favourite girls' name, while Charlotte is just behind. Arthur is the favourite boys' name, followed by James.
