The Russian Ambassador to the UK has urged Britain to be honest when investigating the poisoning of a Russian ex-spy and his daughter.

Speaking at a news conference in London, Alexander Yakovenko asked Britain to share results of the analysis of samples by the international chemical weapons watchdog. The Russian ex-spy poisoning crisis has lasted more than a month. The ex-spy's daughter, Yulia Skripal, issued a statement on Thursday, saying her strength was slowly returning. Yakovenko told the media he's happy to hear that and hopes Yulia will come back to Moscow someday.
