Because Scottish electoral law declares that all registered residents are entitled to vote in all elections, a large number of foreign workers and students will be able to influence the crucial vote while hundreds of thousands of Scots living abroad will not be able to participate, Panorama reported.
Latvia's ambassador to the United Kingdom, Andris Teikmanis, said that while around 4,500 Latvians were registered residents at the time of the last census, the precise number of Latvians eligible to participate was difficult to know.
Around 4.3 million people in all will be eligible to vote.
Scotland goes to the polls on September 18 to decide whether to dissolve its 300-year-old union with England with a simple 'Yes' or 'No' answer to the question: "Should Scotland be an independent country?"
Polls suggest the vote will be a close one... maybe the Latvians will make the difference?
