Talks between the Conservative party and the DUP ended today without a conclusion.
Theresa May insisted the Government was "absolutely steadfast" in its commitment to the Northern Irish peace process as she faced questions on whether a DUP-Tory alliance would put fragile agreements at risk.
"It's a unity of objective, having voted to leave the European Union, that their government gets on with that and makes a success of it".
The Prime Minister did not mention the ongoing deliberations as she addressed MPs but called on Parliament to "come together in a spirit of national unity" to deal with the challenges facing the country. "The reality is that where we stand follows logically from leaving, so, if we're leaving, what we need to do is do it smoothly and successfully and gain economic benefit".
But a newly appointed junior Brexit minister, Steve Baker, told Reuters: "I don't foresee any change".
Guy Verhofstadt, the European Parliament's chief Brexit negotiator, warned the United Kingdom risks a "brutal exit" if discussions aren't concluded within two years.
'I am impatiently waiting for the negotiating position of the United Kingdom government that I hope will be more in line with the will and the interests of the British citizens'.
"Like Alice in Wonderland, not all the doors are the same".
"There's no doubt that there is a new player on the stage", Mr Cameron said.
"Their position on this was very similar to the Conservative position according to their manifesto".
Corbyn told May that if her "coalition of chaos" with the DUP did not work out, Labour stood ready to provide "strong and stable leadership in the national interest".
Earlier, the PM appointed Steve Baker, the hardline Leaver, as a Brexit minister, who said Britain should seek the "softest" of European Union withdrawals while enabling the country to control its own laws, money, borders and trade.
Yet many of her lawmakers and party members favor a sharp break with the European Union - a sign of the divisions over Europe that helped sink the premierships of May's predecessors Margaret Thatcher, John Major and Cameron.
Brexit negotiations officially started in May when the PM signed a letter under Article 50 of the Lisbon Treaty, and are due to end by November 2018.
Whatever her ultimate plan, she will be heavily reliant upon the 10 lawmakers from the eurosceptic DUP, who would help her edge past the 326 votes needed in parliament to avoid the government collapsing.
Talks with the DUP to secure her government broke up on Tuesday night without an agreement, but Mrs May said the discussions had been "productive".
Theresa May will hold talks with political leaders from Northern Ireland as she tries to calm fears her anticipated deal with the DUP will undermine the peace process.
While DUP leader Arlene Foster has now left for Northern Ireland, leaving party colleagues to continue hammering out the details of the arrangement with the Conservatives, the other four main parties at Stormont confirmed they would meet Mrs May on Thursday afternoon.
The EU negotiator said the special nature of the Republic of Ireland and Northern Ireland would be a key element of the talks.
