The wife of Alexei Navalny has accused Vladimir Putin of killing her husband after he was "tortured and starved" as she addressed the EU Parliament.

Yulia Navalnaya said Putin "must answer for what he has done to my country".

She added that her husband's "murder" has shown that "Putin is capable of anything and that you cannot negotiate with him."

Navalny's funeral will take place tomorrow but his family are unsure whether it will be peaceful or "whether the police will arrest those who have come to say goodbye to Alexei."

Addressing the EU Parliament, Navalnaya said her husband inspired people despite the restrictions the Kremlin placed on him.

She said: "Even in Putin's gulag, Alexei managed to pass on ideas for projects that would make the Kremlin panic."

The 47-year-old also warned that Putin cannot be hurt by sanctions or resolutions.

"This is the answer to the question. If you really want to defeat Putin, you have to become an innovator. And you have to stop being boring," she added.

"You can't hurt Putin with another resolution or another set of sanctions that is no different from the previous ones. You can't defeat him by thinking he's a man of principle who has morals and rules."
