Britain's ambassador to Russia held talks with an official at the Russian Foreign Ministry on Wednesday to discuss the poisoning of a former Russian spy and his daughter in Britain, the Interfax news agency cited the ministry as saying.

British prosecutors earlier on Wednesday charged two Russians -- Alexander Petrov and Ruslan Boshirov -- who they said had tried to murder Sergei Skripal and his daughter Yulia with a military-grade nerve agent in England.

British ambassador Laurie Bristow met Igor Neverov, the director of the ministry's second Europe department, Interfax reported.
