[Photo/Agencies] A win for Scotland's pro-independence parties in the United Kingdom's regional elections has increased the pressure for a new referendum on whether the country should go it alone, an option its voters rejected just seven years ago. Much has happened since 2014, not least the UK's Brexit vote and its subsequent departure from the European Union, which most Scottish voters opposed. For that reason alone, a second referendum might stand a better chance of producing a leave vote that would end the 300-year union between Scotland and England. The government in London will try to head off a new vote, but it has no ultimate veto to block it forever.
