The leader of the independence-minded Scottish National Party says her party will never accept British Prime Minister Boris Johnson's Brexit plans.

Nicola Sturgeon told her party conference Tuesday that Scottish voters had opposed leaving the European Union during the 2016 Brexit referendum and are unwilling to be dragged out of the EU.

She compared Johnson to U.S. President Donald Trump, saying both leaders use "crude populism" to trample on the rights of minorities.

Sturgeon said "what leaders like Boris Johnson and Donald Trump have in common is this — a belief that nothing should be allowed to stand in the way of their own self-interest. Not facts or evidence. Not the rule of law. Not democracy."

Sturgeon reiterated plans to try to hold a referendum on Scottish independence next year.
