The national anthem has just been heard at the Queen's funeral.

But did you know there is a line about Scots in the song - which has caused a "number of people" to raise concerns in the past. 

Here's what you need to know about the mention of Scots in the UK national anthem ...

Are Scots mentioned in the national anthem? 

Yes, Scots do feature in the national anthem, but you may not have heard the verse sung before. 

The line about Scots doesn't come into until verse 6, which is not frequently sung during events and in fact has not been played publically for a number of years. 

The verse reads: "Lord grant that Marshal Wade, May by thy mighty aid, Victory bring. May he sedition hush, And like a torrent rush, Rebellious Scots to crush, God Save the King."

It's a tribute to Marshal George Wade, the commander-in-chief of George II's Hanoverian forces, however its inclusion in the anthem has raised questions in the past. 

During Gordon Brown's premiership, the PM ordered a review of British citizenship conducted by former attorney Lord Goldsmith, who suggested that the verse calling for "rebellious Scots" to be crushed should be rewritten.

Speaking in 2007, Lord Goldsmith said: "Quite a number of people have raised the issue of the national anthem in a number of ways.

"I think the national anthem is an important part of our national tradition."

He added: "But the review is about different ways of sharing our tradition and national identity ...

"What we have to look at is different ways of saying what it is that links the country together."

However, in 2010 it was confirmed that no changes would be made to the anthem. 

The debate over the lyrics has been raging for decades, with Billy Connolly first raising the question in the 1980s during his 'appearance on 'An Audience With...' which attracted millions of viewers.

The comedian said of the anthem: "It's an appalling song, and it's racist. The fourth verse is all about Marshal Wade coming up to give us a belt in the mouth."
