Len Goodman on how he became Strictly Come Dancing's TV darling

Updated: 

Head judge Len Goodman has been synonymous with Strictly Come Dancing since it launched in 2004.

The 72-year-old ballroom dancing expert, who has served as head judge on the BBC show for over a decade, will be stepping down after Saturday night's finale.

Len's famous catchphrases include "it's a 10 from Len", "pickle my walnuts" and "se-ven!".

In the US he is best-known for television dance programme Dancing With The Stars (DWTS), splitting his time between Los Angeles and London.

He stepped down as a DWTS judge for the 2015 series to spend more time with his family, but reversed his decision and decided to return a year later.

Bethnal Green-born Len started his career as an apprentice welder in Woolwich and was also a footballer.

He began dancing at the age of 19 and went on to a successful professional dancing career, becoming a four-time British champion.

Aside from his television career, Len runs a ballroom dancing school, the Len Dance Centre, in Kent.

A passionate golfer, he once joked that it was a "shame the work gets in the way of the golf, really".

The Strictly judge is a life-long fan of West Ham United after he first attended a game aged six.

In recent years, Len has turned to documentary-making, looking back on the history of dance as well as his own life.

In 2013, he presented BBC Four programme Len Goodman's Dance Band Days and hosted Len Len's Perfect Christmas on BBC One.

He also presented the BBC Four show Dancing Cheek to Cheek alongside historian Lucy Worsley.

In Len And Ainsley's Big Food Adventure, he teamed up with former Strictly Come Dancing contestant Ainsley Harriott for a 10-part series about world cuisine in England and Wales.

Len has been married twice, firstly to dancing partner Cherry Kingston and, since 2012, to his companion of over 10 years, dance teacher Sue Barrett.

He has one son, James Len.

James has followed in his father's footsteps, teaching Latin and ballroom at the Len Dance Centre.

The Strictly judge has spoken about his joy at becoming a grandfather last year to James's daughter, Alice.

Len was treated for prostate cancer in 2009 but did not take any time off from Strictly or DWTS.
