'Countryfile' has been granted access to Queen Elizabeth's royal residences.

The 92-year-old monarch has agreed to let the cameras into her Sandringham House in Norfolk, Balmoral Castle in Aberdeenshire and Windsor Castle in Berkshire - where Prince Harry will marry Meghan Markle next month - for the show's 30th anniversary.
Presenter Adam Henson said: "I once had the great pleasure of meeting Her Majesty, and in our conversation I soon realised that, like me, she loved her animals. It became clear that the working countryside and her animals were her passion."
The special episodes - which will coincide with the 65th anniversary of the Queen's coronation - will explore the royal's attachment to rural Britain and love of animals.
A BBC spokesperson told the Mail Online: "The show will give unprecedented insight into how these estates are run, revealing how actively involved both The Queen and The Duke have always been in their development."
Executive Editor Bill Lyons said: "It's a privilege to work on 'Countryfile' and a delight that the programme has reached its milestone 30th anniversary.
"We've shared many memorable moments with our viewers during those three decades, but we look to the future and hope to celebrate the beautiful British countryside for many years to come."
The hit show, which has been gracing television screens since 1988, pulls in millions of viewers every week as it focuses on rural and environmental issues across the UK.
It's not yet known which presenters - Helen Skelton, Anita Rani, Ellie Harrison, John Craven, Adam Henson, Matt Baker and Tom Heap - will cover the royal specials.
