Belarussian opposition leader Maria Kolesnikova, who led the mass protests against President Alexander Lukashenko in Belarus last year, has been sentenced to 11 years in prison for extremism and for trying to take power illegally.

Her lawyer Maxim Znak is simultaneously sentenced to ten years in prison, reports the Russian news agency Tass and the opposition in Belarus.

Both deny the crime and Maria Kolesnikova has called the accusations absurd.

Both worked for the presidential candidate Viktor Babaryko before the presidential election in August last year.

Babaryko himself was arrested in June last year on charges of corruption and sentenced to 14 years in prison in early July this year.
