This can cause the political instability which Russia is waiting for.

Former Ukrainian President Petro Poroshenko has returned to Ukraine to fight treason charges he rejects as politically motivated.

“We are here not to defend Poroshenko. We are here to defend Ukraine,” he told a crowd of hundreds of supporters gathered at Kyiv’s airport after arriving on a flight from Warsaw on January 17.

“We have to unite to show that Ukraine is strong and is able to stand against [Russian President Vladimir] Putin’s aggression,” said Poroshenko, who has been out of the country since December.

Meanwhile, Ukraine’s State Bureau of Investigations (DBR) said it had tried to serve a subpoena to the 56-year-old former president, who it claimed refused to take the documents.

Later on January 17, a Kyiv court is expected to rule on whether to remand Poroshenko in custody pending investigation and trial.
