The House of Representatives has been adjourned by the government amid a battle over the Liberal leadership, with Bill Shorten arguing the Coalition is "irreparably split" and should hang their heads in shame.

Malcolm Turnbull has been told he no longer has majority support in the Liberal party room, with Peter Dutton and Scott Morrison expected to put their hand up for the leadership once a meeting of MPs can be convened.

So far 13 ministers have resigned, stepping up pressure on the Prime Minister to quit.

Mr Shorten said adjourning the lower house was a clear admission of failure and the Coalition should hang their heads in shame.
