Ryder Cup £5

The Royal Bank of Scotland has unveiled a special Ryder Cup £5 bank note to commemorate the return of this golfing tournament to Scotland after more than 40 years. It will be legal tender in the UK, but won't go into general circulation. In fact it will cost £20 to buy (CLICK). Is that inflation or what? And where does Scottish independence fit in with this fiver? So far the "debate" has been between Alex Salmond's sunny optimism and the scaremongering gloom of the opposition. Where are the hard facts? How can The Royal Bank of Scotland retain its royal status if it belongs to a foreign country? And who will back up its currency? Alex Salmond?
