The battle for the future of Scotland has begun after a dramatic set of British election results left the U.K. starkly divided.

Prime Minister Boris Johnson¡¯s Conservative party cemented its grip on Labour¡¯s former heartlands in northern England, while in Scotland parties pushing to split away from the U.K. won a historic majority.

That threw Johnson and Scottish National Party leader Nicola Sturgeon into what could be a vicious and lengthy showdown over whether a new referendum should be held over Scottish independence.
