Ukrainian secret services have captured a pro-Kremlin politician and Vladimir Putin ally after weeks on the run - and may trade him for captive prisoners of war (POWs).
Viktor Medvedchuk - dubbed the Prince of Darkness - had escaped house arrest before going AWOL just three days after Russia launched its invasion on February 24.
The 67-year-old is the leader of Ukraine's main opposition party Opposition Platform For Life and has been described as the Russian President's right-hand man over the border.
