The Duchess of Cambridge plans to resume royal duties later this month after being sidelined by a prolonged bout of severe morning sickness.

Palace officials said Friday that Prince William and the former Kate Middleton are scheduled to welcome Singapore president Tony Tan when he arrives on a four-day state visit October 21.

She had canceled a number of engagements after her second pregnancy was announced in early September. Officials said at the time she was being treated for acute morning sickness at the family quarters in Kensington Palace.

The condition also marked the first trimester of her first pregnancy, when she was carrying Prince George.

Officials said Kate's participation in the welcoming ceremony will be reviewed in the coming weeks.
