Britain's Prince William, grandson of Queen Elizabeth, and his wife Kate are expecting their second baby and the mother-to-be is once again suffering from very acute morning sickness, his office said on Monday.
The baby will be fourth-in-line to the British throne, following elder brother George, the couple's first child who was born in July last year, his father William and grandfather Prince Charles.
"The Queen and members of both families are delighted with the news that their royal highnesses are expecting their second child," Buckingham Palace said in a statement.
