The publication reports William Hill have placed the odds at 8/11 on Meghan giving birth to a daughter, and that the name Diana is at 10/1 odds.

Victoria is also a strong contender.

"We are still taking bets on gender - we are 8/11 for a girl, so the betting is suggesting there's a great chance it's a girl."

The names Isabella and Alice are at 12/1 odds, followed by Elizabeth and Grace at 16/1.

If the couple welcome a baby boy, the current favourite with the bookies for names is Arthur, followed by Philip, James and Edward.
