What significant issue led to calls for a second referendum on Scottish independence?

The calls for a second referendum on Scottish independence were significantly influenced by Brexit. When the United Kingdom voted to leave the European Union in 2016, the outcome revealed a deep division in public opinion, particularly in Scotland, where a majority of voters favored remaining in the EU. This disparity created a belief among many Scots that their interests were not being represented within the UK, as they would be leaving the EU against their will.

The Brexit process also raised concerns about Scotland’s future economic and political landscape, leading to discussions about whether Scotland should seek independence to rejoin the EU as a sovereign nation. Supporters of a second referendum argued that the political dynamics had fundamentally changed post-Brexit, which justified a new vote on independence. This issue has been central to the political discourse in Scotland and has re-energized the independence movement, making it a key factor in the continued push for a second referendum.
