Quotation from “The Telegraph”:

Leading bookmaker Coral is continuing to see a flurry of bets on:

Mary – it is now the 4-1 favourite. 

Alice is second best in the latest betting, 

Victoria is 8-1 and

Albert can be backed at 12-1. 

Mary is one of the Queen’s middle names, and it was also her grand-mother’s name – Queen Mary – who was married to George V. So, apparently a girl is expected at the Cambridges. Lady Helen Mary Stewart-Wilson will be pleased with all the references to her (second) Christian name 🙂 .
