As politicians meet in Europe to discuss border controls, campaigners in Norway have proposed moving their own border west – to give their neighbours in Finland a mountain.

A social media campaign launched by Bjorn Geirr Harsson, a retired employee of the Norwegian Mapping Authority, suggests Norway could shift its eastern border 20 metres (66 feet) so that the Halti mountain peak could become part of Finland.

The proposal was intended as a gift to celebrate the 100-year anniversary of Finland's independence in 2017.

"We would not have to give away any part of Norway. It would barely be noticeable," said Mr Harsson, 75, speaking to the Norweigian website, The Local. “And I’m sure the Finns would greatly appreciate getting it.”

The Halti is only 1,365m (4,479ft) tall, placing it well out of the list of Norway's top 200 highest peaks.

But Finland has no mountain peaks of its own, so even the Halti’s lowest slopes would become Finland's highest peak.

His campaign page on Facebook adds: "Not only will this be a great gift, but how many countries can brag about having given a mountain as a gift?"

Mr Harsson came up with the idea having flown over Norway for business and wondered why only part of the mountain was inside Finland.

He took his proposal to Anne Cathrine Frostrup, his former employer and head of the NMA, who backed the idea.
