During his early years there he achieved critical acclaim for his performances in Carnaval and Spectre de la Rose.
Following a period of military service he rejoined the Sadler's Wells Theatre Ballet as a principal dancer in 1951.
Known for his masculine, aggressive style, a number of leading solo parts were created for Britton by the leading choreographers of their time - Frederick Ashton (Valses Nobles et Sentimentales), Kenneth MacMillan (Danses Concertantes, Solitaire (1956) and The Burrow (1958)), Walter Gore (Carte Blanche) and John Cranko (the title role in Sweeney Todd).
Britton also had a mischievous, lighthearted side which was seen to good effect in his portrayals of Captain Belaye in Pineapple Poll and Pierrot in Cranko's Harlequin in April.
He continued to dance during this time in a number of West End musicals including The Grand Waltz then went on to further teaching in the Arts Educational Schools in London.
