Foreign Secretary Dominic Raab said the UK does not accept the results of the “fraudulent” presidential election in Belarus following consecutive days of protests against the government of Alexander Lukashenko.
Protests in Belarus have continued to rage against the rule of Alexander Lukashenko.
Demonstrators have repeatedly taken to the streets since the August 9 election which saw Mr Lukashenko claim victory.
But it has been condemned as rigged by critics at home and abroad as workers are expected to strike today in protest.
Mr Raab said the vote had been “fraudulent” and he condemned the violence from the Belarusian authorities as they attempted to crack down on the protests.
The Foreign Secretary's comments come three days after the European Union said it did not recognise the results.
He called for an independent investigation by the Organisation for Security and Co-operation in Europe (OSCE).
Mr Raab said: “The world has watched with horror at the violence used by the Belarusian authorities to suppress the peaceful protests that followed this fraudulent presidential election.
“The UK does not accept the results.
"We urgently need an independent investigation through the OSCE into the flaws that rendered the election unfair, as well as the grisly repression that followed.
“The UK will work with our international partners to sanction those responsible, and hold the Belarusian authorities to account.”
Mr Lukashenko has ruled the ex-Soviet nation with an iron fist since 1994.
He has rejected any possibility of repeating the vote that gave him a sixth term, lashing out at the West and declaring his country will “perish as a state” if the election is rerun.
