But Conor Burns MP, a vocal supporter of Mr Johnson, said it was "bizarre" for Commissioner Dick to use her position to look into the comments with rising crime in the Capital. She said she welcomed an investigation, "but let's not pretend this is an isolated incident".
The panel will decide whether to refer Johnson to the party's board.
Absent from the 2016 leadership contest when key allies withdrew their support on the eve of his campaign launch, Mr Johnson failed to bring any statesmanship to the Foreign Office.
