The betting frenzy on the royal pregnancy has been suspended after punters betting on Kate Middleton having twins sent odds tumbling.
The William Hill betting firm, who received 200 bets on arrival of twins, refused to take any further bets, when a series of new accounts were opened and the odds plunged to 9/1, the Daily Express reported.
Hill spokesman Rupert Adams said that they have had a load of unexpected bets including a large number of new accounts, with any other market that people know.
British odds-makers came up with predictions about the second royal baby's name and gender after Buckingham Palace announced on September 8 that the royal couple was expecting their second child.
