Putin greetings stir doubts and show of support amid power struggle rumors

Footage of Putin being enthusiastically greeted in Dagestan came after a turbulent week that raised questions about his leadership.
Videos of Putin kissing fans fueled speculation that he used a body double, though there's no evidence to support those claims.
The images were likely intended to portray Putin as still firmly in control after reports of an advance on Moscow by Wagner troops.
The Kremlin denied a challenge to Putin's power and said the reception showed the public's support for him.
Speculation has long swirled that Putin employs doubles for some public appearances, though Moscow rejects those theories.
