The leader of City of Edinburgh Council has resigned after police launched an investigation into an allegation of inappropriate behaviour.
Labour's Cammy Day had been suspended by the party pending the outcome of the probe.
It was reported by the Sunday Mail that Day had "bombarded" Ukrainian refugees with messages, including asking sexually explicit questions.
He confirmed his decision to stand down as council leader in a letter to the chief executive.
He said in a statement: "The recent commentary on my personal life is detracting from the important work this Labour-led council does for the people of Edinburgh.
"It undermines the dedicated efforts of my colleagues and council officers.
"That's why it's time for me to step aside as leader."
Day said he had not yet been contacted by police, but said he would fully cooperate with their investigation.
He added: "I am hugely proud of what we've achieved for the capital during my time as leader and truly believe that Edinburgh is a better, fairer city as a result.
"I'm also proud to have led a way of successfully doing politics across divides, finding a way to deliver on our priorities for our people and our city.
"I love Edinburgh and it has been an enormous privilege to have played a part in its success."
The resignation of Cammy Day has the potential to lead to a change in the administration in Edinburgh - not simply a new council leader.
In Scottish councils, it is rare for one party to have an overall majority.
There is no rule which says the single biggest party has to be part of the administration. Deals have to be done.
In Edinburgh, the SNP is the single biggest party but is in opposition.
Instead Labour governs as a minority with support from Lib Dem and Conservative councillors.
Labour will be hoping to stay in charge of the administration but this is not a foregone conclusion.
