WA Senator Linda Reynolds settled with the ACT Government for $90,000 over allegations of misconduct during a rape trial.

Former chief prosecutor Shane Drumgold accused Reynolds of coaching the defence in the trial of Brittany Higgins and Bruce Lehrmann.

The settlement includes $70,000 in damages, $20,000 for legal fees, a formal apology, and a retraction of allegations against Reynolds.

Reynolds has had five successful legal actions, with another case involving Brittany Higgins and David Sharaz still ongoing.

Shane Drumgold has filed a legal claim against the inquiry report that led to the allegations.

Senator Reynolds has not made any public comments regarding the settlement.
