Labour MP Tulip Siddiq has been sentenced by a court in Bangladesh to two years in prison for corruption involving a government land project.
Her aunt, ousted prime minister Sheikh Hasina, was sentenced to five years.
Ms Siddiq, who is MP for Hampstead and Highgate in London, has denied the allegations.
The Associated Press reports Rabiul Alam, the judge of Dhakaâs Special Judgeâs Court, said Ms Hasina misused her power as prime minister.
He also said Ms Siddiq was guilty of corruptly influencing her aunt in helping her mother get a piece of land in a government project.
Ms Siddiqâs mother, Sheikh Rehana, was given seven years in prison and was reportedly considered the prime participant in the case.
The three women are out of the country and were tried in absentia.
Ms Siddiqâs lawyers have called the charges baseless and politically motivated.
She previously told The Guardian the charges against her were âcompletely absurdâ and asserted she was âcollateral damageâ in the longstanding feud between her aunt and Bangladeshâs interim leader Muhammad Yunus.
The UK does not have an extradition treaty in place with Bangladesh.
The Hampstead and Highgate MP resigned from her ministerial job in the Treasury earlier this year following an investigation by the Prime Ministerâs ethics adviser into her links to Ms Hasinaâs regime, which was overthrown last year.
She came under scrutiny over her use of properties in London linked to her auntâs allies.
Although Sir Laurie Magnus concluded that Ms Siddiq had not breached the Ministerial Code, he advised Sir Keir Starmer to reconsider her responsibilities.
Ms Siddiq chose to resign, saying she had become âa distractionâ from the Governmentâs agenda.
