He remained with the series from 2005 until 2022.
The telly star started his career as a welder and only became interested in dancing when his doctor told him to take it up to help him recover from a foot injury.
Len went on to become a successful professional dancer, winning titles including the British Exhibition Championships and the World Exhibition Championships and later continued his love of dance after retiring by forming the Goodman Dance Academy in Kent to help others achieve their dreams.
After finding fame on TV, he chronicled his rise to fame in his 2009 memoir Better Late Than Never: From Barrow Boy to Ballroom and went on to publish two more tomes - Len’s Lost London and Dancing Around Britain.
He announced his retirement from Dancing with the Stars last year and on his final episode, he was presented with his own Mirrorball trophy.
Len said of the honour: “That is fantastic. It has been such a joy for me to have been part of Dancing with the Stars. It really has. I’ve had such a wonderful time and this is absolutely the cherry on the cake.”
