It now seems unlikely that the UK government will secure a transitional agreement with the EU in time for businesses to postpone their plans to start leaving the UK or cutting their investments there. If so, the percentage of British voters who come to realize that Brexit represents a real threat to their jobs and incomes can only grow. If the last year and a half has revealed anything about British politics, it is the instability of public opinion. If the polling numbers start to move strongly against Brexit, the political class will surely take note and start moving toward the only solution that makes sense for Britain: to abandon the whole disastrous project altogether.
