Carole and Michael Middleton

Carole and Michael Middleton, who are the parents of Britain's Duchess of Cambridge, have landed in Mustique to celebrate Carole's 61st birthday on Sunday (31.01.16), HELLO! magazine reports.

It is not yet known whether the Duke and Duchess of Cambridge or their children Prince George, two, and Princess Charlotte, eight months, will join them.

Meanwhile, Carole and her other daughter Pippa are keen party planners and recently shared their top tips for a perfect Christmas.

Taking to their Party Pieces blog, they wrote: "Brainstorm all the jobs you need to do in preparation for Christmas and put it up on your pinboard at home. Mark off the jobs as you do them and give yourself an extra day to get everything done. Think what food you can prepare in advance, (things like sauces, brandy butter etc), what you can freeze and try to avoid the supermarkets during the weekday evening rush and at weekends.

"It's always useful to update your address book, in preparation for sending out Christmas cards. You could always get your computer-savvy child to help you type out all the addresses to avoid having to use your scribbled out address book."
