River deep

Think the Thames is the only river in London? Think again. There are several - but they've all been buried beneath the city, converted into sewers.

Fair play to James Bowdidge of the Tyburn Angling Society, who want to restore the River Tyburn as "a prime fishing stream". You have to admire anyone who can describe a proposal that "would require destruction of billions of pounds worth of property including Buckingham Palace" as "very realistic"...
