Ian Blackford has urged Rishi Sunak to "admit that Brexit is a significant long-term cause of the UK economic crisis."The Scottish National Party's Westminster leader asked when the prime minister will "finally see reality."In his address to the Commons, Blackford called the EU exit the “elephant in the room that neither the Tories or Labour are willing to confront.”Sunak, in response, said he was "proud to support Brexit" as it was the "right thing" for the UK and gives back "control of our borders."Source: PA
