The Tories and the DUP are considering a "confidence and supply" arrangement which would see the Northern Irish party back the Government to get its Budget through and on confidence motions.
"I want to record my deep-seated concern and, I believe, the deep-seated concern of many, not just in Scotland but across the United Kingdom right now, at the prospect of some sort of grubby deal between the Tories and the DUP to allow Theresa May to cling to office", she said. Foster said discussions were going well.
After House Speaker John Bercow was re-elected without challenge, a chastened May quipped: "At least someone got a landslide".
May had called the vote early in hopes of strengthening her majority going into talks on exiting the European Union, but instead found herself in negotiations with a small party in Northern Ireland in order to stay in power.
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. "I am dubious about it", Major said.
Barnier held "talks about talks" with May's Brexit advisor Olly Robbins and British EU Ambassador Tim Barrow in Brussels on Monday but they failed to agree on a date for the negotiations to begin, an EU official said.
Following London talks with the DUP, May will head to Paris to meet with French President Emmanuel Macron who has just won an impressive victory in parliamentary elections.
May is under pressure to take on a more cross-party approach to the negotiations surrounding Brexit.
Trump Under Investigation For Obstruction Of Justice
Asked if that constituted obstruction of justice, he said: "That's a conclusion I'm sure the special counsel will work towards". Asked whether Trump's actions rose to the level of obstruction of justice, Comey testified last week: "I don't know".
May faced Conservative party lawmakers at a meeting of its 1922 Committee.
"There's no doubt about that, but perhaps an opportunity to consult more widely with the other parties on how best we can achieve it", he said at a conference in Poland.
The UK government wants the talks to take place in parallel during the Brexit process but both sides have made finding a solution to the issue of citizens' rights a priority.
Divisions over Europe helped sink the premierships of Ms May's predecessors Margaret Thatcher, John Major and Cameron, and many of her lawmakers and party members favour a sharp break with the EU.
The stakes for May are high.
May formally asked Queen Elizabeth II for permission to form a minority government, which would mean a coalition or informal deal would be necessary with another party.
"My preoccupation is that time is passing - it's passing quicker than anyone believes - because the subjects we need to deal with are extraordinarily complex from a technical, judicial and financial point of view".
