MEPs will later vote on whether the UK should seek EU permission to postpone Brexit beyond 29 March.
Backbench MPs and Opposition parties have tabled eleven amendments to show what they want to do next.
Speaker John Bercow has selected four amendments to the debate, although not all are expected to be put to the vote at 1
But his decision to call for another referendum – but not another referendum – was called into question by some Brexis.
Tory Brexiteer Mark Francois said that he was signed by "127 members of this House, including the entire DUP, 13 members of the Labor Party and an independent relative" as well as more than 100 Conservative MPs Bercow, why it had not been selected ,
Mr. Bercow said to him, "Members need to take the rough with the Smooth," and he always tried "to do my best to meet the different points of view."
The government's request for a debate on Thursday reads:
(1) takes note of Parliament's resolutions of 12 and 13 March, and accordingly agrees that the government should agree with the The European Union agrees to extend the deadline referred to in Article 50 (3);
(2) agrees that if the House has passed a resolution regarding the negotiated resignation agreement and the framework for the future relationship for these purposes is approved by § 13 (1) (b) of the European Union (Withdrawal) Law 2018 until 20 March 2019, then the Government will try to extend the one referred to in Article 50 (3) with the European Union To settle the necessary period of EU exit legislation, and
(3) notes that if the house is no Resolution has passed the negotiated resignation agreement and the framework for the future relationship within the meaning of Section 13 (1) (b) of the European Union (resignation) 2018 until 20 March 2019, then it is very likely that the European Council At its meeting the following day, it would have a clear purpose for any extension, not least for the determination of its length, and would require an extension beyond 30 June 2019 would force the United Kingdom to hold European Parliament elections in May 2019.
Here are the amendments adopted for debate:
The bipartisan amendment (h) of independent MPs Sarah Wollaston, SNPs Philippa Whitford and Joanna Cherry, of Lib Dem Tom Brake and Neil Coyle of Labor calls for another referendum and would be the first to be elected.
It amends the wording of the Government Proposal and calls on the Prime Minister to request an extension of the procedure under Article 50 "sufficient to enact laws and conduct a public vote in which UK citizens consent to The European Union may resign on conditions to be determined by Parliament or to maintain the membership of the United Kingdom in the European Union. "
If supported, the following two amendments – by Hilary Benn and the Front Bank of the European Parliament – would be withdrawn Labor Party – not voting and MEPs would be asked to vote on Chris Bryant's amendment next.
If rejected, MEPs would vote on the next on this list.
Labor will not support this amendment as it is n It is not the time to push for further public voting and reduce its chances of success.
This bipartisan amendment (i) would allow MEPs to take control of the process in Parliament on Wednesday, March 20, in order to force a series of directives into Brexit's preferred option for MEPs to establish.
It is supported by Senior Backbenchers: Hilary Benn and Yvette Cooper of Labor, Sir Oliver Letwin and Dominic Grieve of the Conservatives, Lib Norman Lamb and Stewart Hosie of SNP.

In the House of Commons, Benn said he would support an amendment to his amendment by Labor MPs Lucy Powell, which complements this. Any expansion of the Brexit process should end by June 30.
In a separate move, Cabinet Secretary David Lidington said that the government would be rejected a second time by MEPs two weeks after Theresa May rejected the deal for the third time in the following European Council debate on 21 and 22 March, to enable the commons to find a majority for another plan.
The BBC's political correspondent, Vicki Young, said it seems the government is trying to attack the Benn amendment, a good chance to get through.
If Members refuse, they will be asked to vote on the Labor Frontbank amendment next.
If they support this, they will not vote on the change of the Labor Party and will vote directly on the amendment by Chris Bryant.
