Vladimir Putin is facing a multimillion-dollar legal action for his alleged role in the shooting down of a Malaysia Airlines passenger jet over eastern Ukraine.
British lawyers are preparing a class action against the Russian President through the American courts. Senior Russian military commanders and politicians close to Mr Putin are also likely to become embroiled in the legal claim.
The case would further damage relations between Mr Putin and the West, but politicians would be powerless to prevent it.
Last week, lawyers from McCue & Partners, the London law firm, flew to Ukraine for discussions about how to bring the case and where it should be filed. Victims' families will be invited to join the action. The case will inevitably highlight the role allegedly played by Russia in stoking conflict in eastern Ukraine.
A representative from the family of British-born Kiwi Rob Ayley, killed on the flight, said "there was no comment".
