Greenland's nearest equivalent to Plaid Cymru has won the recent Parliamentary Elections there. Greenland recently achieved a record level of autonomy from Denmark, and Inuit Ataqatigiit ('Inuit Community'), a leftist party promoting socialism and Greenlandic nationalism will now lead the government. They won 43% of the vote, increasing their seats from 14 to 31 in the Greenlandic parliament. The social democratic Siumut have been ousted for the first time in 30 years.
As they are very much a youth-dominated party, it could be worth Cymru X building links with them. Their programme of government should be interesting, although it will undoubtedly be hard to find up to date news about politics in Greenland.
