Sir Paul McCartney is set to release a cookbook filled with recipes from his late wife Linda McCartney

Paul will release ‘Linda McCartney's Family Kitchen: Over 90 Plant-Based Recipes to Save the Planet and Nourish the Soul’ alongside his and Linda’s daughters Mary, 51, and Stella, 49, on June 29.

According to a press release, the book will feature a collection of Linda’s best-loved recipes reimagined for the modern cook, and will "bring Linda's kitchen up to date, reinventing her best-loved recipes for the plant-based cook, alongside their favourite family stories and the dishes that they now eat at home”.

And in a statement, Paul said: "Years ago, before anyone had woken up to the idea of environmental and health and animal welfare issues, Linda was blazing the trail with vegetarianism, telling people about it and promoting it. At home, she would cook for the family and these recipes have been now brought up to date for a modern audience, so they're all now plant-based and fabulous.

"In the book there are family photographs and stories from those days, and of course lots of great, beautiful-tasting healthy recipes. So I hope this book inspires conversations about sustainability and about modern living amongst people besides also just giving them some great recipes to eat."

The 78-year-old musician has tried to encourage other people to follow a vegetarian diet over the years as he previously banned animal food products from his rider.

The meat-free demands were reportedly part of the terms and conditions of Paul playing in the province of Saskatchewan in Canada in 2013 - meaning he wouldn't perform unless show organisers confirmed no meat would be eaten backstage.

He also made a similar demand in 2002 when he was on his 'Driving' USA tour as he said he didn't want any furniture in his dressing room to be made of animals.

It reportedly said: "It is crucial you do not provide furniture made of any animal skin or print. Do not provide artificial versions of animal skin or print either. Only animal free materials are excepted. (cottons, denims, velour, etc.)"
