G4S Olympic contract review prompts two resignations

Two G4S directors have resigned after the company announced the findings of a review into its Olympic Games contract.

The two are David Taylor-Smith, chief operating officer, and Ian Horseman Sewell, a managing director.

The company was paid a £57m fee to supply Olympics security staff, but had to rely on the army for back-up after failing to fill the posts.
