Douglas Alexander MP, Shadow Foreign Secretary said:

“The shocking murder of former Russian deputy prime minister Boris Nemtsov has rightly drawn widespread international criticism and condemnation.

"Mr Nemtsov was a committed democrat, and made a lasting contribution to politics in Russia, including being an outspoken critic of the conflict in Ukraine.

"The priority now must be a thorough and impartial investigation into this brutal murder. Clearly President Putin has a responsibility to show that the Russian authorities are willing and able to take the appropriate steps to identify Mr Nemtsov’s killers and bring them to justice.”
