Alfie, Alexandra and Diana are bookies' favourite names for Harry and Meghan's second baby

Prince Harry and Meghan Markle could name their second child after his mother Diana if bookies have got their odds right.
Diana is one of the bookies' favourite names for the royal baby, at odds of 6/1 with Ladbrokes, while Betfair are also seeing the name prove popular with punters.
It would mean the child would share a name with her cousin too, as Princess Charlotte's middle name is Diana.
Alex Apati of Ladbrokes said: "Royal punters are seemingly convinced Harry and Meghan's second born will be named after his mother, regardless of whether it's a boy or a girl, as Diana and Spencer are currently proving the most popular picks in the betting."
However, Diana and Spencer are not the most popular options among bookmakers. The names Alfie and Alexandra are both at 4/1 in the stakes with Ladbrokes, while Arthur is also a favourite at 10/1 with Betfair.
Thomas is at 12/1 with Betfair, which would see the royal child named after his maternal grandfather, Thomas Markle.
The Duchess of Sussex is not in contact with her father, and recently won a privacy claim in the High Court over the Mail On Sunday's decision to print extracts of a letter she wrote to him in 2018.
Andrew also features at 18/1, despite the forced stepping back of Harry's uncle Prince Andrew, over his links to the disgraced financier Jeffrey Epstein.
Other family names appearing in the odds lists include Camilla at 66/1, William at 100/1 and Doria, Meghan's mother's name, is at 25/1.
Philip, which would see the child named after Harry's grandfather, is at 18/1, while Charles is at 16/1.

The baby will be eighth in line to the throne, and the first royal baby to be born outside of the UK.
The birth in the US will mean he or she will be able to run for President.
Despite the baby being unlikely to live a royal life, some names of past kings have made it into the top spots in the odds list.
Albert is at 12/1 with Betfair while Edward is 14/1.
Betfair said more people are betting on girls' names than boys, at 75% of bets to 25%.

Betfair spokesperson Sam Rosbottom said: "Having picked Archie - a name that wasn’t even on our list, for their first child - the odds suggest Meghan and Prince Harry could opt for a more traditional name for their second with Arthur and Diana the joint 10/1 favourites with Betfair.
"Meanwhile, we have seen a big move for Thomas into 12/1 second favourite from way out at 100/1 - while Abigail, a new name on the list, is straight into 14/1 third favourite.
"July 2021 is the favourite month for the birth in the betting so far, while Alice, Diana and Spencer are proving the most popular names so far with Betfair punters - who are also favouring girls names at 75% of the bets compared to boys names at 25%."
Harry and Meghan announced their pregnancy on Sunday 14 February with a new black and white photo shot remotely by their friend Misan Harriman.
The couple said they were excited to confirm that Archie, their firstborn, was going to be a big brother.
The Duke and Duchess of Sussex have not said when she is due to give birth.
