The original manuscript of one of the world's best-known songs could fetch £50,000 when it goes under the hammer later this year, auctioneers have said.

But in an unusual twist, the buyer of the fragment of Robert Burns' manuscript for Auld Lang Syne will not be able to take it home.

Instead, the winning bidder will become the"patron" of the rare Scottish artefact.

The manuscript of the song – sung across the world at New Year – will be housed in a new museum dedicated to the bard in his native Ayrshire.
