The BBC’s Last Night of the Proms is meant to be the moment that Britons unite in a moment of patriotic singing of standards like Rule, Britannia! and Land Of Hope And Glory.

The corporation organises live “Proms in the Park” open air concerts in England, Scotland, Wales and Northern Ireland every year to coincide with the Last Night’s broadcasts from the Royal Albert Hall in London.

However, the broadcaster has been caught up in a political row after it prevented fans at the live concerts in Scotland and Wales from singing along to the songs with audience members at the hall in London.

On Saturday night all four concerts featured a live feed of the BBC concert orchestra playing Sir Henry Wood’s sea shanties from his Fantasia on British Sea Songs from the Royal Albert Hall.
