May, who became prime minister after the June 2016 referendum on leaving the European Union, had called the election three years early in a bid to strengthen her hand in the looming Brexit negotiations.
Davidson, one of the few Conservatives to emerge as a victor from the election after she increased the party's presence in Scotland, said she had demanded, and received, "categoric assurance" from May that the policy would not change.
May is seeking a loose "confidence and supply" arrangement with the DUP's 10 MPs that would allow her to press ahead with a minority government, after losing her Commons majority in general election. Corbyn says there's enough opposition in Parliament and in May's own party to topple the government. May had relied on Timothy and Hill for advice and support since her previous job at the interior ministry, and their resignations will be a personal blow. Prime Minister Theresa May and her Conservative Party's representation in Parliament fell to 318 MPs - eight seats shy of keeping an outright majority in the Parliament - while Corbyn's Labour Party brought their representation to 262 MPs. The DUP, which won 10 seats, said it is ready to talk with May about supporting her government.
The announcement came after thousands of anti-DUP protesters marched on Downing Street againt the "hateful" alliance between Mrs May and the socially hardline party.
Scottish Conservative leader Ruth Davidson, who took the party from one Scottish seat to 13, said there would now have to be "consensus within the country about what it means and what we seek to achieve as we leave".

Instead of betting on the size of the majority, party insiders were now putting money on when the prime minister would quit, less than a year after she was propelled into Downing Street following Britain's shock decision to exit the EU.
DUP leader Arlene Foster said "we have made good progress but the discussions continue".

The stunning poll outcome now leaves May battling to unite different factions of her party and reliant on a handful of Northern Irish parliamentarians just nine days before Britain starts the tortuous process of negotiating its departure from the EU.
Former Treasury chief George Osborne - who was sacked by May a year ago - called May a "dead woman walking", and Labour leader Jeremy Corbyn said he was ready to contest another election at any time.
