And finally… survey finds third of English people would refuse Scottish money

The firm showed images of notes from the Bank of Scotland, Royal Bank of Scotland and Clydesdale Bank to 1,710 people, and only just over three quarters were unable to identify where the currency was from.

One in six believed that the notes were out of circulation and about one in ten was unsure of the exchange rate between Scotland and England.

Nearly a quarter of respondents said that they would reject the notes.

Royal Bank of Scotland notes were the least likely to be accepted by those questioned; one in five believed that these were fake.

Scottish notes are legal currency, meaning that they are approved by the UK parliament, but they are not legal tender, even in Scotland.

This month Scottish Liberal Democrat deputy leader Alistair Carmichael lodged a Bill in the House of Commons calling for Scottish banknotes to be accepted throughout the UK.

Mr Carmichael will present his Legal Tender (Scottish Banknotes) Bill to Parliament as he bids to encourage businesses across the United Kingdom to recognise and accept Scottish banknotes.

The Lib Dems say the Bill would enhance the status of Scottish banknotes and mean a distinction couldn’t be made between these and other banknotes issued in the UK when accepting them as payment.

Responding to the Censuswide findings, Mr Carmichael said: “These figures show just how common it is for people elsewhere in the UK to be confused by Scottish currency. If you’re Scottish or Northern Irish, chances are that you will have a tale of a time that your banknotes were met with bafflement.

“The UK government need to encourage businesses across the UK to recognise and accept these notes.

“Alongside giving their support for the measure outlined in my bill, they should also launch a public awareness campaign to boost public knowledge of the different types of banknotes in use across these islands.”
