Foreign Secretary Dominic Raab has announced sanctions against Belarusian leader Alexander Lukashenko.
Others, including Mr Lukashenko’s son Viktor and members of his government, also face penalties – including frozen assets and travel bans.
The eastern European nation has been gripped by protests since the disputed election held on 9 August.
Despite many – including the UK – claiming that the results were rigged, Mr Lukashenko was sworn in as president in a secret ceremony last week.
Mr Raab said on Tuesday: “Today the UK and Canada have sent a clear message by imposing sanctions against Alexander Lukashenko’s violent and fraudulent regime.
“We don’t accept the results of this rigged election.
“We will hold those responsible for the thuggery deployed against the Belarusian people to account and we will stand up for our values of democracy and human rights.”
The full list of those hit by the sanctions is:
- Alexander Lukashenko, the president
- Viktor Lukashenko, his son and national security adviser
- Igor Petrovich Sergeenko, the president’s chief of staff
- Yuri Karayev, the minister of internal affairs
- Alexander Barsukov, the chief of public security police
- Yuri Nazarenko, commander of internal troops
- Khazalbek Atabekov, deputy commander of internal troops
- Dmitry Balaba, commander of the special purpose police unit of Minsk
