On Sunday, Kazakhstan will hold a snap presidential vote expected to cement incumbent Kassym-Jomart Tokayev's grip on power, months after deadly unrest shook the Central Asian country and left more than 230 people dead.The National Security Committee said a group of seven people planned to "organise riots and a coup and proclaim a provisional government," adding that the suspects "share the views of exiled opponent Mukhtar Ablyazov".Tokayev, 69, became leader in 2019 and has stymied opposition and consolidated power by sidelining his authoritarian predecessor Nursultan Nazarbayev after the January unrest.Tokayev has vowed to build "a new Kazakhstan" by liberalising the judicial system, tackling corruption and undertaking reforms.The International Monetary Fund has warned of the persistent risk of instability as Kazakhstan's economy -- heavily dependent on Russia -- is suffering from the impact of the war in Ukraine."
