Gardiner sent the chilling warning, that an “increasingly deranged and deluded” Putin could resort to the “occupation” of Ukraine and “quite likely ethnic cleansing, as well as mass killing.”

Putin is becoming more and more desperate each day and Gardiner warned he could be preparing to set up “concentration camps, inflicting horrific, horrendous suffering on the Ukrainian people.”

The foreign policy expert told Express.co.uk, “Putin poses a huge threat to the freedom of the world today. This invasion is an act of barbarism and complete madness.

“Putin looks increasingly deranged and unhinged.

“These are extraordinarily dangerous times and I’m very concerned about what comes next.”

Gardiner warned: “Putin will follow the invasion with occupation and quite likely ethnic cleansing in Ukraine, as well as mass killing.

“We should be prepared for the possibility of Putin setting up concentration camps, and inflicting horrific, horrendous suffering on the Ukrainian people.

“He is capable of genocide – he doesn’t care at all about human life.

“We are looking at savagery and barbarism on an epic scale with Putin, so we cannot underestimate what is happening and what might happen.”

On Saturday, the Office of the UN’s human rights office had recorded the deaths of 847 civilians in Ukraine since 24 February.

This also includes injuries of 1,399 civilians, but they “believe that the actual figures are considerably higher.”
