After having spent the best part of last week in Majorca, it is back to school for Princesses Beatrice and Eugenie on Monday - but if their mother, Sarah Ferguson, goes ahead with her plan to buy a house on the island, there will be plenty more visits during their school holidays. Eugenie aged 11 and Beatrice aged 12, behaved like the true Princesses they are as they bid farewell to Majorca at Palma's private jet terminal on Friday, shaking everybody's hand and thanking them - including the chauffeur of their Mercedes. The two girls however attend different schools. Beatrice attends St George's School in Ascot and her younger sister this year started at St George's private school near Windsor Castle - home to their favourite grandmother, according to Sarah Ferguson. Ferguson, who has admitted to being a huge fan of the Queen and calls her the Boss, has said that the two Princesses have a special set of table manners for when the Boss is around and the two girls showed their impeccable manners at Palma airport. Sarah Ferguson had been expecting her ex-husband, Prince Andrew the Duke of York, to have briefly joined the family in Majorca, but the Prince was apparently forced to alter his plans at the last minute. She has spoken of her love for Majorca before as well as a desire to buy a home on the island. The Duchess, who was plagued by financial problems for years, earlier this year netted an estimated £400'000 for a commercial she made for American television in which she appeared as a cash-strapped former Royal whose fairytale marriage ended on the rocks.
