In the past couple of years，with the Scottish National Party consolidating its position as the dominant party in Scotland in both national and local elections，the bid for a second independence referendum gained momentum. The SNP took advantage of Brexit and the pandemic to actively campaign for a second referendum. Despite the opposition of the British government，the SNP formally proposed a roadmap for a second independence referendum in June 2022. However，there is still considerable procedural uncertainty around a second independence referendum and no clear swing in Scottish public opinion in favour of independence. In the next few years，the UK and the Scottish local government will continue to fight over the second independence referendum. Although it is difficult for the Scottish National Party to hold the second independence referendum as scheduled in 2023，the constitutional uncertainties in Scotland will continue to create challenges for the UK in the future.
