How has Brexit impacted the UK's relationship with Scotland and Wales?

Since the UK's decision to leave the European Union, the relationship between the UK, Scotland and Wales has become more complicated. Scotland and Wales voted to remain in the EU, but were outvoted by the rest of the UK. This has led to tension between the devolved governments and the UK government.

Scotland has been particularly vocal about its desire to remain in the EU, and this has led to renewed calls for Scottish independence. The Scottish National Party (SNP) has argued that the Brexit vote has changed the circumstances of the 2014 Scottish independence referendum, and that Scotland should be given another vote on independence. In Wales, there has been less talk of independence, but Welsh nationalists have argued that the Welsh government should have a greater say in the Brexit negotiations.
