Pauline Hanson tells Sky News she is actively considering moving to the lower house at the next election and that she could do the job of prime minister.

Hanson says a move back to the lower house, where she was first elected in 1996, is “a consideration by all means”.

I believe that I have the ability to do it.

I’m not going to underestimate myself or say ‘no, I can’t do it’, because you know, have a look at what we’ve got now, really honestly, and that’s why we’re in a mess.

Those people who work overtime do their 40 hours a week or 38 hours a week, they’re working overtime, they’re taxed to the hilt, and I think we need to overhaul the whole taxation system.
