Absolutely Fabulous is to return to BBC One later this year with three specials to celebrate the show's 20th anniversary.

Jennifer Saunders and Joanna Lumley will return as Edina and Patsy along with other original cast members.

Saunders told Mark Lawson on Radio 4's Front Row that Edina and Patsy are "more desperate" as they age.
