The crisis engulfing Australia’s politics has continued to grow following the emergence of videos showing staff members performing sex acts in parliament, leading to one senior aide being fired.

One video showed the aide performing a sex act on a female MP’s desk.

Prime Minister Scott Morrison described the videos as “disgraceful”.

It comes after a former staff member revealed how she feared losing her job following an alleged sexual assault.

Brittany Higgins alleges she was raped by senior colleague in an office in March 2019, but says she felt pressured not to report the incident to police.
