"UltImately the Government must give a final say through a People's Vote, with the option to remain in the European Union".
The British government suffered a major blow on Tuesday when it lost a parliamentary vote on legal advice it received on the Brexit deal agreed with European Union leaders last month.
Andrea Leadsom, Leader of the House of Commons, said on Tuesday that this had been a "full and frank exposition", and that releasing the full advice would set a unsafe precedent.
The proceedings against the government for contempt of Parliament could potentially result in one or more ministers being suspended or expelled from the House of Commons.
"By treating Parliament with contempt, the Government has proved it has lost its majority and the respect of the House".
The row threatened to overshadow the start of five days of debate in Parliament on Ms May's Brexit deal ahead of a crucial vote on December 11, when MPs will be asked to approve it.
Support for Theresa May's Brexit deal has faded since its high watermark last week. Pro-EU lawmakers and the DUP, which props up her government, say they will vote against, and the main opposition Labour Party says it will try to unseat her.
Chris Leslie, the Labour backbencher backing the amendment, said: "MPs are going to gradually assert their rights - including the right to instruct the government in future stages".
Mr Grieve said: "Parliament has tonight asserted its sovereignty to ensure that amendments - such as for a People's Vote - can be made to any motion if or when the Government's proposed deal for leaving the European Union has been defeated".
If she loses, May could call for a second vote on the deal.

Xi's administration also hopes talks will exclude or sideline key trade hawks, such as Trump adviser Peter Navarro. Whether such a cease-fire would be enough to get Trump to delay higher or expanded tariffs is unclear.
Opposition parties say their representatives will vote against the deal, and so have dozens of lawmakers from May's Conservative Party.
"But the reality remains that we have an unsatisfactory procedure to resolve differences of opinion in this House, if and obviously, it's an if, we come to a point where the Government does not succeed on its motion and the opportunity exists this afternoon to cure that anomaly".
"We have tested the opinion of the House twice on this very serious subject", Andrea Leadsom, the leader of the House of Commons said after the vote took place.
These concerns are not likely to derail the Brexit debates; however, the deal will probably not pass on its first reading based on Parliamentary arithmetic and May's minority conservative government.
In an opinion prepared for the European Court of Justice (ECJ) in Strasbourg, the advocate general said the United Kingdom did not need the approval of the 27 remaining EU member states to halt the two-year countdown triggered invoking Article 50 of the Lisbon Treaty.
"I'm focusing on ... getting that vote and getting the vote over the line", she said.
She also said Parliament would be consulted on the government's negotiating mandate as it embarks on talks on the UK's future relationship with the EU.
In the most extreme no-deal scenario, shopping bills could rise by up to 10% but even in an orderly no-deal withdrawal, with a transition period, grocery prices could rise by 6%, he said.
"It is a tribute to the perseverance of the Scottish parliamentarians involved that we will finally get clarity from the Court of Justice on this important question".
