Views from Edinburgh on what Brexit means for Scotland
David Cameron is in Brussels negotiating an agreement on the European Union.
If an agreement is reached, the way is paved for the prime minister to hold a referendum on the UK's membership which could take place in June.
Polls have suggested that Scotland is more likely than any other part of the UK to vote to remain in the EU.
BBC Scotland political correspondent Nick Eardley has been to Edinburgh to hear the views of people there.
