Polly (The Curse of Clyde Langer)

From Tardis Wiki, the free Doctor Who reference

Polly was a homeless woman who was living on the streets of Ealing in 2011.

Before she became homeless, she had worked in the City. The other homeless people called her Polly the Porsche because she was telling everyone what car she used to drive. Polly pushed everything she had got around in an old trolley. (TV: The Curse of Clyde Langer)
