As China continues to flex its financial muscle by buying into British airports, water and breakfast cereals, Antony Barnett investigates the nation's growing economic power. The programme tells the behind-the-scenes story of the Dalai Lama's visit to Britain earlier this year and reveals details of how politicians from the Highlands to the heart of Westminster are influenced by the Chinese government. The latest instalment of Stephen Fry: Gadget Man follows at 8.30pm. There is indeed a lot on Channel 4 tonight. Lord Alan Sugar is on it this evening.
