Nicola Sturgeon has branded Boris Johnson the "worst Prime Minister" in her lifetime after he used his final speech to take a swipe at her plans to hold another independence referendum.
The First Minister and the outgoing Tory PM have not seen eye-to-eye over the last three years with SNP leader saying Johnson had brought "chaos" to the country during his time in charge.
During his farewell speech on the steps of Downing Street the former Conservative leader took a thinly veiled swipe at the FM saying, "those who want to break it (the union) up, they'll keep trying, but they will never, ever succeed".
