The Standard also reported that US and British officials are expected to plan for a full state visit for Trump sometime in the future.
He is due to make a "working visit" which wouldn't feature the pageantry, or a stay with the Queen, that a state visit would include.
The Evening Standard, which is edited by George Osborne, a former finance minister fired by May a year ago, reported that diplomats were discussing plans for a pared-down working visit, devoid of the pomp of a full state visit.
The prospect of a state visit by the US President - an invitation extended to him by Prime Minister Theresa May just seven days after he took office - has sparked controversy, with London Mayor Sadiq Khan among those opposed to the idea.
Trump's working visit will focus on global security discussions, according to the Evening Standard.
They said a full state visit will follow later at an unspecified date.
Downing Street declined to comment on the trip and said its position on the state visit had not changed.
Thousands of people launched protests against the move, while more than a million people signed a petition to stop the trip from going ahead.
In the meantime Trump has visited Emmanuel Macron in Paris for Bastille Day festivities, held talks with Angela Merkel in Hamburg, toured the Vatican and met the Pope, visited Belgium's King Philippe at the Royal palace in Brussels and held talks with European Union leaders at their headquarters.
'Exact dates for President Trump to visit have not yet been arranged'.
The newspaper said its view was that "any USA president is welcome in London".
