The Rwandan authorities have auctioned off assets from the family business of Diane Rwigara – a jailed critic of President Paul Kagame who was barred from running in last year’s election.
She is facing a charge of forgery as well as inciting insurrection – a charge her mother is also in prison for.
The Rwanda Revenue Authority sold the machinery from the family’s tobacco business for almost $2m (£1.5m) as it tries to recover around $7m it says is owed in tax arrears.
The family says the auction of the assets and all the charges are politically motivated.
She had planned to run against Mr Kagame in the 2017 elections, but was disqualified from doing so by the election commission.
Mr Kagame won the poll with 98.63% of the vote.
