Britain is drifting towards disaster on Brexit — without a viable diplomatic, economic or political strategy to make a success of the venture.

The central problem is that the British government is stuck between an implacable EU and an unrealistic Conservative party. The EU will not offer anything like the deal that Britain’s Brexiters still dream of. But Theresa May’s Conservative colleagues are still unprepared to accept this unpleasant reality.

In this paralysing situation, it seems increasingly likely the UK government will simply be politically and technically incapable of delivering a negotiated Brexit. As a result, the likeliest outcome is that, late in the day — perhaps in January 2019 — the EU will present Britain with a “take it or leave it” deal.
