Royal baby Henry will spark second round of celebrations

Also on the drift is James from 2/1 favourite to 4/1, with George the new market leader after being supported from 5/1 into 2/1.

Alexander is another name to have been backed slightly into 7/1, with Louis, one of William’s middle names, joining Henry among the 12/1 offerings.

William is the 4/7 favourite to be holding the baby when the family leave hospital, with Kate 6/4 in this market, while it is 8/11 that the couple announce that they are having a second child ahead of brother Harry getting married.

It is 1/1 that 2015 is the year that Kate and William announce that they are having a second child and William has a two-year age gap with Harry.

Alternatively, 2/1 is the price that they announce the baby next year and there is only a single year between Kate and her sister Pippa.

Punters prepared to wait for a successful payday can take advantage of odds of 8/1 that the Royal baby, who is third in line, ascends the throne before 2065, while it is 1/1 that he takes over after.

All Odds and Markets are correct as of the date of publishing.
