The report said Putin was so scared of being assassinated that he was refusing to travel abroad.
Dmitry Medvedev, a Kremlin official and former Russian president, said a drone attack on the Kremlin in May was a Ukrainian attempt to assassinate Putin, which Ukraine denied.
Ingram's comments echo those of a former Kremlin security official, Gleb Karakulov, who fled Russia in April in opposition to the war in Ukraine.
Ingram said Putin's isolation meant he was only being presented with distorted information by a group of close aides, warping his decision-making.
Ingram said Putin would like to portray himself as an "international statesman" who asserts himself on the global stage.
