Instead of using the question posed in the 2014 referendum ("Should Scotland be an independent country?"), some polls have adopted the remain / leave formulation that was used in the 2016 Brexit referendum. In the context of Scottish independence, this means that the question would be asked in the fashion of "Should Scotland remain in the United Kingdom or leave the United Kingdom?". The use of this format has been criticised by Scottish nationalists; SNP depute leader Keith Brown said in September 2019 that it was "a deliberate bid to confuse independence with Brexit".
