Theresa May has said she intends to form a government that will provide "certainty" and guide the country through Brexit talks.
Mrs May said she was confident the Tories would be able to work together with the Democratic Unionist Party in the "interests of the whole UK".
Speaking outside Number 10, she said: "This Government will guide the country through the crucial Brexit talks that begin in just 10 days and deliver on the will of the British people by taking the United Kingdom out of the European Union.
"It will work to keep our nation safe and secure by delivering the change that I set out following the appalling attacks in Manchester and London.
"We will fulfil the promise of Brexit together and, over the next five years, build a country in which no-one and no community is left behind.
"What the country needs more than ever is certainty...now let's get to work."
Veteran David Winnick failed to defend Walsall North where his majority was less than 2,000. He had held his seat there since 1979.
Keith Wilkinson reports from Walsall:
Andy Street, the Conservatives' West Midlands metro mayor, who beat Labour in the mayoral election last month, said Theresa May should stay on as Prime Minister but needed to start "listening".
Mr Street, former managing director of John Lewis, contrasted the "hope, optimism and inclusivity" of his own successful campaign run with the tone of the Conservatives' General Election pitch.
Speaking on BBC Radio 5 Live, he added that the Tories had failed to hammer home the message on economic stability and that "the risk around that changing, wasn't made clear around the last few weeks".
While backing Mrs May to stay on in the top job, he added: "The mark of the real leader is listening to what is being said over the last 24 hours."
