Is a delay in triggering Brexit counter-productive?

The most ardent campaigners for Britain remaining in the European Union would like the debate on withdrawal to go on forever, or at least until a new government or a new referendum could repudiate the referendum vote to leave taken last June. By contrast, the victors have secured the prime minister’s commitment to start official negotiations no later than the end of March by triggering Article 50. Doing so will begin two years of discussions between London and Brussels, terminating before Easter 2019 with the UK no longer an EU member state.
