THE Clydesdale Bank has launched a commemorative £20 banknote to celebrate the enthronement of Robert the Bruce as King of Scots 700 years ago.

Lord Elgin, who is the 37th Chief of the Bruce clan and a bloodline descendent of the Scottish hero, has agreed to allow Bruce's original heraldic shield - depicting a lion and a Saltire - to be used on the notes.

The Bruce family came over from France in 1050 and were granted the lands of Annandale, in the south of Scotland.

Robert the Bruce, the 7th chief, became the Earl of Annandale and Carrick, before being crowned King of Scotland at Scone in 1306.

Unveiling the note, Scottish Secretary Douglas Alexander said: "It is a welcome opportunity to celebrate a great Scottish hero and acknowledge the work of a successful Scottish business.

"The Clydesdale Bank is making an important contribution to the current strength of both the Scottish, and UK, economy."

David Thorburn, of Clydesdale Bank, said: "We are delighted that our well-known Bruce banknote has been updated to commemorate the 700th anniversary."

Clydesdale notes have commemorated great Scots since the early 1980s, when Bruce was placed on the £1 note. The others are: Robert Burns (£5); Mary Slessor (£10) Adam Smith (£50), and Lord Kelvin (£100).
