A bookmaker in Britain has suspended betting on the birth of a royal heir in 2013 amid a surge in wagers.
The Daily Star newspaper reported on Friday that punters went into a frenzy after a visit by Prince William and Catherine to Cambridge on Wednesday where the couple displayed "broody" behaviour.
"Betting went through the roof again this week," Coral spokesman David Stevens told the paper.
"We cut the odds 1-4 and then again to 1-8, at which point we decided to suspend the betting."
During the visit, Prince William received a gift of a home-made baby jumpsuit emblazoned with the words "Daddy's little co-pilot".
AFP reports he gladly accepted the gift, saying: "I'll keep that."
Ladbrokes cut their odds on Catherine giving birth in 2013 to 1-5, with twins at 33-1.
