In recent months Davies has faced criticism from some Westminster Conservatives about the direction of the party.
Supporters of Davies say he was attempting to tackle the threat of Nigel Farage’s Reform UK, taking the party in a more right-leaning direction, while opponents are concerned the party is not trying to broaden its support.
His leadership saw him oppose four Welsh Labour first ministers, but Davies never came close to dislodging Labour’s dominance of Welsh devolved politics.
But under his leadership the party returned a record number of seats at the last Senedd election in 2021.
He has courted controversy with his social media account. In the summer comments about halal meat led to accusations from a Muslim group of “race-baiting”.
Former Welsh Tory Senedd leader Lord Bourne also criticised a message on X which showed Davies asking constituents if they thought the Senedd should be abolished.
The party officially supports Wales’ system of government, with the Welsh Parliament and Welsh government controlling the NHS, education, agriculture and councils, among other areas.
It comes after a poll at the weekend suggested the Conservatives were in fourth place in Wales, behind Plaid Cymru, Reform and Labour.
Last week, Davies wrote: “A group of Senedd members approached me, threatening to resign their positions in shadow cabinet if I did not agree to step down as leader.
“I therefore requested a motion of confidence in my leadership to be held at a meeting this morning.
“This vote has now taken place. It was clear from the result that a substantial minority of the group do not support our approach, despite it being the only viable strategy available.
“While I would have been honoured to continue as leader, my position is consequently untenable.”
