Putin seeks 'constructive dialogue' with UK's Johnson: Kremlin

"I am sure that the development of constructive dialogue and cooperation in various spheres would be fully in the interests of our countries' peoples and the entire European continent," he said in a statement.

Earlier Friday the Kremlin said it doubted however that Johnson's election victory would change Russian-UK ties for the better.

Putin's spokesman Dmitry Peskov said that Moscow always hopes an election brings to power voices in favour of "good relations" with Russia but was not sure that would be the case with Johnson's Conservative Party.

"I don't know to what extent such expectations are appropriate in the case of the Conservatives," Peskov told journalists.

Fragile ties between Moscow and London have been shredded after the 2018 poisoning of the former Russian spy and double agent Sergei Skripal, which the UK has blamed on Russia.

The incident led to dozens of tit-for-tat diplomatic expulsions.

Russia has repeatedly denied any part in his killing.

The case had strong echoes of the poisoning of former Russian agent Alexander Litvinenko in Britain in 2006.
