British police have arrested a suspect in the killing of Ann Widdecombe, a former British member of Parliament and reality TV contestant. Widdecombe, who was 78, was found dead in her home in southwest England on Thursday with serious injuries. A 26-year-old British man is in custody. That's according to Devon and Cornwall Police. Authorities say the crime is not being treated as terror-related or politically motivated. Widdecombe was a former Conservative lawmaker and later joined the Brexit Party. She was known for her socially conservative views and appearances on reality TV shows, such as Strictly Come Dancing.
