Russian investor on doing business in the UK

David Cameron is due to visit Russia to try to kick-start relations with the country.

The UK-Russian relationship has been strained in recent years - particularly since the murder in London of former Russian spy Alexander Litvinenko.

But political tensions have not stopped the Russian elite from embracing the UK and the British way of life.

Russian businessman Grigory Guselnikov recently bought the Rolex flagship store at One Hyde Park in London. He tells the BBC's Moscow correspondent Steve Rosenberg why he likes doing business in the UK.
