While the Georgian government has sought his extradition for years, his troubles in Ukraine make that prospect more likely.
Saakashvili served as Georgia's third president from 2004-2007 and again from 2008-2013.
Conviction of a president for using his unrestricted right to pardon convicts indicates the political nature of the trial, - former President of Georgia Mikheil Saakashvilisaid when commenting on the verdict delivered by Tbilisi City Court against him, InterPressNews reported.
Now, Mr. Saakashvili wrote, Mr. Ivanishvili and President Poroshenko are coordinating the legal actions against him in Ukraine and Georgia.
According to the Prosecutor's Office, few weeks after Girgvliani's murder in 2006, Mikheil Saakashvili promised Data Akhalaia, then head of the the Interior Ministry's Department of Constitutional Security, to pardon those officials from the same Department, who would be willing to claim responsibility for the murder, and would not reveal the identities of those who ordered and committed the murder.
A court in the Georgian capital, Tbilisi, sentenced Saakashvili on Friday.
Saakashvili opposed the court ruling, saying it was "unlawful".
He became an outspoken critic of the Ukrainian president and accused him of carrying out corruption.
To judge a president for exercising pardoning powers is a politicized move, he added. "This 'decision, ' as well as the parallel legal process in Kiev, clearly demonstrates that the oligarchic governments in both Ukraine and Georgia are working - in a synchronized and completely coordinated fashion with each other - against me".
Khatia Dekanoidze, a member of Saakashvili's United National Movement party in Georgia, said the January 5 verdict in Tbilisi might help Ukrainian authorities extradite Saakashvili to Georgia.
Putin "repeated that in his recent press conference", the 50-year-old Saakashvili said, claiming that talks aimed at "neutralizing" him were conducted between Ukrainian President Petro Poroshenko and Ivanishvili in Georgia several days before Poroshenko issued an order to strip him of his Ukrainian citizenship last summer.
His Georgian citizenship was revoked when he got Ukrainian nationality in 2015.
