The fire was under control by 6.35pm and crews from Millwall, Poplar, Shadwell and Whitechapel fire stations attended the scene.

A London Fire Brigade spokesperson said: "The fire was caused by the unsafe disposal of smoking material."

They issued advice to smokers, adding: "It's safer to smoke outside, but make sure cigarettes are put right out and disposed of properly."
