Mrs May, who had called a snap election confident her Conservative Party would increase its majority and strengthen her hand in the Brexit talks, yesterday said she would lead a minority government backed by the DUP.
On a day full of unanswered questions, one thing is certain: that clock is ticking.
Detailed negotiations haven't yet started, however.
Brexit negotiations could now be dragged out even further after Theresa May failed to get an overall majority in the general election.
"We don't know when Brexit talks start". "We know when they must end".
On Friday, European Council president Donald Tusk warned Mrs May there is "no time to lose". "The worries are unnecessary and they shouldn't have them but we want to make sure they are dealt with as quickly as possible".
Already, some banks have started moving jobs out of the United Kingdom and into other European countries because they fear they'll lose business after Brexit if they don't.
More immediately the survey found that nearly half (46 per cent) of employers who employ EU/EEA nationals do not expect any change in the number of EU nationals in their workforce over the next 12 months.
That's a problem for European officials who had seemed to come to grips with the notion of Brexit and were ready to deal with an empowered May.
The main sticking points remain the size of the U.K.'s exit bill, which is estimated between 60 billion to 100 billion euros ($67.2 billion to $111.9 billion) and a deal on citizens rights on both side, including any role for the European Court of Justice, noted analysts at BlackRock.
That is highly unlikely, although not impossible.
He added, however, that anti-EU elements of May's Conservative Party might resist attempts to soften the party's tone.
However, the result could have a big impact on the final shape of Brexit.
There was a more conciliatory tone towards May from France.
Mr Davis insisted he was loyal to Mrs May, telling ITV's Good Morning Britain: "There is a distinction between running a campaign and running a country".
On Ireland, such a scenario appears hugely complicated without raising some form of trade barriers between Northern Ireland and the rest of the UK.
Hogan said another British election might be needed to give a government a mandate to make the hard decisions required to secure a Brexit deal, as May was "very damaged" as a result of the poll.
In Brussels on Wednesday Barnier instead met Olly Robbins, a senior official in Davis's ministry, and Britain's ambassador to the EU Tim Barrow to discuss arrangements for the talks following the election shock.
No party has gained a clear majority, something the British prime minister was hoping would not happen.
But crashing out of the European Union without some kind of deal now looks much less likely.
