In short:

Senator Jacinta Nampijinpa Price's defection to the Liberal Party has been criticised by some insiders as an attempt to assist the party's conservative wing.

But she says the Liberal Party needs strong people "more than ever" in the wake of its election loss.

What's next?

The Liberal Party is expected to meet at 10am on Tuesday in Canberra to elect a leader of the opposition and a deputy.
