Diana revealed as the favorite royal name of Meghan Markle and Prince Harry

The royal baby is on the way, but will Meghan Markle and Prince Harry opt for tradition or sentimentality about the name?

The former actress being in the last phase of her pregnancy, bettors have difficulty in determining the bad, weight, date and place of birth of the baby.

One of the most popular bets is his name – with Diana as his favorite.

For a boy, Arthur runs the bookmaker group William Hill, but if it's a girl, many expect the Duke and Duchess of Susbad to pay homage to Harry's late mother.

"Diana (is) the favorite red / 1 / 10th, no big surprise there," said William Hill spokesman Rupert Adams. "But the recent move also concerns the Victoria 10/1 (people) really like it."

The grandson of Queen Elizabeth and his American wife, who was married last May, announced in October that they were expecting their first child this spring.

In January, Meghan announced to a goodwill that she was six months pregnant, adding that the couple did not know the bad of the baby.

William Hill's odds were 8/11 for a girl and even for a boy earlier this week. At Betfair, the odds have been reduced for a girl and the favorite name is Diana at age 5, said Katie Baylis, Betfair Media Relations Manager.

Baylis said that another possibility was Alice, a name that was among those speculated when Prince William and his wife Kate were expecting their third child last year. Kate finally gave birth to a boy, Prince Louis.

"The bettors believe that there will be at one time an Alice in the royal family and so we have seen a strong interest also for this name," she said.

Prince Philip's mother, Harry's grandfather, called Alice.

Betfair has a rating of 8/1 for Arthur. Alice, Victoria, Grace, James and Edward each stand at 14/1. Diana and Arthur are also among the favorites of other bookmakers.

Other bets included who will be the baby's godparents, the date and time of birth and whether Meghan will have twins.

"Compared to (Prince William and Kate), bets on Harry are significantly more numerous at this point, so about 30% (more) … in real terms, it's huge," Adams said.

Outside Buckingham Palace, tourists shared their name preferences.

"I would put money on a girl and on Victoria (as a name) because we could call her Tori," said tourist Sarah Owens.

Mary, another visitor, chose Mary: "(This) seems very old-fashioned, but it's Meghan and Harry (combined)."
