Theresa May - who called the snap election to strengthen her government ahead of Brexit - lost her absolute majority after dropping 12 seats. Thornberry was asked how Labour would able to form a minority government instead of the Conservatives and responded: "We would put forward a Queen's Speech and a Budget".
Jeremy Corbyn, the Labour leader, has urged Mrs May to resign, saying she should "go and make way for a government that is truly representative of this country".
May, who had called for snap elections in the hope of increasing the Tory majority and strengthening her hand in Brexit negotiations, met the Queen on Friday and announced that she would form a minority government with the DUP to proceed with Brexit despite her party's failure in the Thursday election. May (who said the European Union would find her "a bloody hard woman") or any other future prime minister will find it tough to steer a path forward. Theresa May promised strong and stable leadership.
The Conservatives "have lost their majority and the prime minister has lost all authority and credibility" - Scottish First Minister Nicola Sturgeon.
In the 2015 general election, Labour won 232 seats under former leader Ed Miliband, down from the 258 seats secured in 2010.
May faced pressure to quit from opposition parties after a troubled campaign overshadowed by two terror attacks, but said Britain "needs a period of stability". The result leaves her fortunes as party leader and prime minister hanging by a thread.
"It's important to have a Government that can take the Brexit negotiations through".
The Labour party and DUP have worked together in the past, but the latter joining hands with Labour was ruled out due to Corbyn being its leader: Corbyn has always been associated with DUP's rival in trouble-torn Northern Ireland politics, Sinn Fein.
"I think Corbyn was underestimated massively", Kevin Hector, a fifty-year-old worker at Swiss bank UBS, told AFP on Friday. "And giving the police and the authorities the powers they need to keep our country safe", she continued.
With just a few stragglers yet to declare their results it appears that, although the Conservative Party has remained the top vote-getter, it has shed over a dozen MPs. His seven months in office, in 1922-23, earned him the sobriquet of "the unknown prime minister".
"We might have a softer version of Brexit, a smoother transition", noted Wilson at ETX.
"Substantive Brexit negotiations were unlikely to happen until after the German elections in the autumn, so there is time for both the United Kingdom and the rest of the European Union to think through where negotiations might go next", he said.
She now risks more opposition to her Brexit plans from inside and outside her party.
May said Brexit talks would begin on June 19 as scheduled, the same day as the formal reopening of parliament. An uncompromising demand for a hard break from Europe may have to be downgraded to a far more modest rupture, Kearns said, perhaps even one that doesn't look much like an exit at all.
