The Duke and Duchess of York are said to have rekindled their romance with one source suggesting they could even remarry.

Sarah Ferguson and Prince Andrew, both 53, have remained close since their split in 1996.

A friend told the Sunday Telegraph: "Mark my words, they will remarry."

They have two daughters, the princesses Beatrice, 25, and Eugenie, 23.

Another source said: "It wouldn’t surprise me at all. They are a wonderful couple together and, better still, pretty amazing parents," reports the Daily Mail.

The Duchess joined her former husband on a trip to Balmoral earlier this month, the first time she had been invited to the estate since notoriously being photographed having her toes sucked by John Bryan in 1992.

The pair have both been linked to a number of relationships since their split but none have worked out.
