Network Ten will seek to prove former Liberal Party staffer Bruce Lehrmann raped his then-colleague Brittany Higgins in its defence against a defamation claim.
Mr Lehrmann launched defamation action against Network Ten and News Corp for their coverage of rape allegations made by his former colleague.
Ten filed its defence with the Federal Court on Tuesday night, joining with journalist Lisa Wilkinson who is also seeking to prove the allegation true as part of her own defence.
