Two Victorian MPs and several Andrews government advisers were present at a rowdy Labor branch meeting in Melbourne’s western suburbs on Saturday where a factional figure was punched in the head.

The incident, where more than 100 people stormed the Tarneit home chanting "let us join the ALP", threatens to ignite a fresh round of factional feuding within the Victorian party amid allegations of branch stacking.

ALP branch member and factional figure Jasvinder Sidhu was assaulted at his home during a branch meeting on Saturday.

Tarneit MP Sarah Connolly and Western Metro MP Kaushaliya Vaghela were among the crowd at the meeting and were captured on video when Jasvinder Sidhu, a factional figure and former candidate, was assaulted at a Hoppers Crossings ALP branch meeting at his parents' home.

Also among the gathering were five staff members of Ms Vaghela, several of whom are employed by Local Government Minister and factional heavyweight Adem Somyurek, an aide to Assistant Treasurer Robin Scott and staffer to federal Labor MP, Daniel Mulino.
