May, who has come under fire for failing to set out a vision for Brexit, told parliament Wednesday that the government would produce a white paper that would be scrutinized by lawmakers.
"I set out that bold plan for global Britain last week, and I recognize there is an appetite in this House to see that plan set out in a white paper," she said a Prime Minister's Questions in parliament on Wednesday.
"I can confirm to the house that the plan will be set out in a white paper published in this house."
May's government had previously argued that revealing details of the plan would jeopardize the country's position in negotiations with the EU.
But calls for a concrete Brexit plan from May's government have grown louder since last week when the prime minister gave a speech in which she set out some broad parameters for Brexit.
She made clear for the first time that the country would not seek to remain in the union's single market and customs union, essentially a free trade area that also allows the free movement of labor.
May told the House of Commons that the white paper would be separate from the bill that would be introduced this week to pave the way for triggering Article 50, the formal process of leaving the EU.
The government was forced to give lawmakers a vote on Article 50 after losing a legal challenge at the Supreme Court on Tuesday.
But the government brushed off the ruling, saying it was still on track to trigger the article and begin the Brexit process by the end of March.
Jeremy Corbyn, leader of the main opposition Labour party, criticized the May government for challenging the legal case, saying it had been a waste of 80 days.
"Could we know when this white paper is going to be available to us and why it's taken so long to get it?" Corbyn asked during the questions session.
"I and this government are focusing on the outcomes," May responded.
"We're focusing on a truly global Britain, building a stronger future for this country, the right deal for Britain ... out of the European Union," she said, describing her plan as "bold."
