Basem Abdo, a Palestinian-Australian communication specialist, has been endorsed by retiring Labor MP Maria Vamvakinou as her successor in the federal seat of Calwell.

Vamvakinou, known for her support of Palestinian statehood, believes Abdo's commitment to social and economic issues will be crucial for peace in the region.

Abdo has significant support within Labor's socialist left faction and aims to connect with Calwell's culturally diverse population, particularly its sizable Muslim demographic.

The endorsement of Abdo is seen as addressing concerns about Labor's response to conflicts in the Middle East, including the Palestinian-Israeli conflict.

If elected, Abdo could offer a unique perspective on these issues.

Vamvakinou's endorsement of Abdo reflects a broader push for greater diversity and representation within the Labor party.
