Sandi Toksvig discusses the 'Wild East' - Russia - with the BBC's former Moscow correspondent, Martin Sixsmith. Actor Michael Simkins relates his adventures on a rail journey from London to Kiev and on to Crimea to visit the former site of the Charge of the Light Brigade at the Battle of Balaklava in 1854 - and author and linguist Anna Shevchenko explains why she believes Ukraine, where she was born, is a 'hidden' country with much to offer the traveller.
