Asked for his Brexit solution to avoid a hard border on the island of Ireland, a leading member of the U.K.'s main opposition party dropped a bombshell.
"Oh, what a temptation," said Shadow Chancellor of the Exchequer John McDonnell, who would be in charge of the nation's finances if Labour came to power. "I long for a united Ireland but I recognize democracy."
It was a throwaway comment — "I'm a Republican" — but one that comes at a delicate time in Brexit negotiations that have become mired in the debate over how to keep the border between Ireland and Northern Ireland invisible when the U.K. quits the European Union.
