Bruce Lehrmann's defamation trial against Network Ten and journalist Lisa Wilkinson is expected to wrap up today, after four weeks in the Federal Court.The case brought by the former Liberal staffer argued he was defamed when allegations by his former colleague, Brittany Higgins, that she had been raped by an unnamed staffer at Parliament House in March 2019, were broadcast in an interview on The Project. Mr Lehrmann has always maintained his innocence, and a criminal case against him in the ACT Supreme Court was abandoned due to juror misconduct.
