An Algerian court sentenced two former prime ministers to long jail terms Tuesday in the first of a series of high-profile corruption trials launched after longtime president Abdelaziz Bouteflika resigned in the face of mass protests in April.

The verdicts came just two days before Algeria is due to elect a president to replace Bouteflika in a vote bitterly opposed by the country's nine-month-old protest movement, which sees it as a regime ploy to cling to power.

Former prime ministers Ahmed Ouyahia and Abdelmalek Sellal, who were both close to the ousted president, were sentenced to 15 years and 12 years respectively.

It was the first time since Algeria's independence from France in 1962 that former prime ministers were put on trial.

The state prosecutor had sought 20-year prison sentences for the two ex-premiers.

In all, 19 defendants were tried on charges ranging from money laundering to abuse of office and granting undue privileges in the nascent vehicle assembly industry. The Algerian automotive sector got its start in 2014, via partnerships between foreign groups and large Algerian corporations, many of which are owned by businessmen linked to Bouteflika's entourage.
