Two contenders for top Vic Liberal job

Former treasurer Michael O'Brien and former planning minister Matthew Guy are expected to vie for the leadership of Victoria's defeated Liberal Party.

They are seen as the most likely contenders to succeed outgoing premier Denis Napthine as a Liberal party room meeting is tipped for this week when it begins to dissect its state election loss.

The changing of the guard will include a new deputy leader, with Louise Asher announcing she will step down from the role after 11-and-a-half years.
