British Prime Minister Theresa May will set out her vision on Friday for a Brexit deal deeper and wider than any "free trade agreement anywhere in the world", telling the European Union it is in their "shared interest".
In a much-anticipated speech which the EU hopes will offer details of her plan for Britain's future after Brexit, May will try to defuse a dispute over the border with Ireland that threatens to stall the Brexit talks.
But the prime
minister, weak after losing her parliamentary majority last year, will struggle to satisfy the demands not only of EU officials but also of the warring factions in her Conservative party and companies desperate for clarity.
The 61-year-old leader has long kept her cards to her chest, trying to avoid provoking those who want a clean break with the EU, or others, who fear the world's sixth-largest economy will be hit if barriers are raised against a major trading partner.
