Glynis Johns, the actress, who has died aged 100, rose to fame in the late 1940s and early 1950s in a series of film comedies; she became best-known for playing the suffragette mother Mrs Banks in the Walt Disney classic Mary Poppins, while on stage her distinctive, husky voice – described by one critic as sounding like “a princess who is turning into a frog” – was perfect for Send in the Clowns in A Little Night Music, the Broadway hit for which she won a Best Musical Actress Tony award.
