Britain's government said on Wednesday it would hand over to Parliament what it called an initial analysis of the impact of Brexit, trying to deflect accusations that ministers are badly prepared for leaving the EU.

The leaked report has struck at the heart of government Brexit strategy, with one minister suggesting that analysis by officials should be discounted and another urging the government to reconsider its stance.

It has piled pressure on Prime Minister Theresa May, who is under fire from some in her own Conservative Party for lacking leadership and a clear Brexit plan, as she negotiates a deal to end more than 40 years of union.
