Former Conservative minister Ann Widdecombe gave a final interview just 20 minutes before police believe she was attacked in her Dartmoor home.
The interview, which was pre-recorded and never broadcast, has now been published by Times Radio after permission was given by Widdecombe's family.
In the clip, Widdecombe defends Nigel Farage's financial conduct, saying the register of MPs' interests had become too broad and that she had to declare all her earnings, regardless of whether they influenced her vote.
Widdecombe, who most recently acted as Reform's justice spokesperson, also joked about having to declare the fee she received for appearing with Basil Brush, saying it was unlikely to influence her vote on hunting.
Farage faced two investigations by the Standards Commissioner over whether he should have formally declared a £5 million 'gift' from a crypto billionaire and support from convicted fraudster George Cottrell.
In the interview, Widdecombe supported Farage's decision to call a 'people versus the establishment' by-election, which was being pre-recorded rather than broadcast live.
Widdecombe's death is being treated as an act of terrorism, with counter-terror police taking over the investigation.
Home Secretary Shabana Mahmood said the case raises questions about the security of those in public life, and offered Farage a meeting with the chair of RAVEC, the independent body in the Home Office responsible for providing security for public figures.
