Alexei Navalny, the Russian opposition leader, was killed by dart frog poison administered by the Russian state two years ago, a multi-intelligence agency inquiry has found, according to a statement released by five countries, the UK, France, Germany, Sweden and the Netherlands.

The US was not one of the intelligence agencies making the claim.

Navalny died in a remote Arctic penal colony where he was serving a 19-year sentence. Samples from his body were secured before his burial and sent to the laboratories of two countries.
