Labour MP and former minister Tulip Siddiq has described her two year prison sentence in Bangladesh as "deeply unfair" after a court convicted her in her absence on corruption charges.

She was found guilty of influencing her aunt, Bangladesh's ousted Prime Minister Sheikh Hasina, to secure a plot of land for her family in the outskirts of the capital Dhaka, a claim she strongly denies.

Siddiq, who is based in London and has rejected the charges, is unlikely to serve the jail term.

The Labour MP said the process had been "flawed and farcical from the beginning to the end".

"I'm absolutely baffled by the whole thing - I've still had no contact whatsoever from the Bangladeshi authorities despite them spreading malicious allegations about me for a year-and-a-half now," she said.
