A 28-year-old man has been arrested for the murder of Ann Widdecombe.
The man was arrested at a South Yorkshire address, Devon and Cornwall police said.
The suspect is a white British national and now in police custody.
The force added there was still no information to suggest it was a terrorism related incident.
South Yorkshire Police and Counter Terrorism Policing North East carried out the arrest on behalf of the Devon and Cornwall Police.
This follows the release of a 26-year-old white British male, who was arrested at an address in Newton Abbot.
Devon and Cornwall Police Assistant Chief Constable Matt Longman previously said the case was moving at a "significant pace".
The force found the former Conservative MP and Brexit Party MEP dead at her home in Haytor on Devon on Thursday after sustaining "serious injuries".
Police believe she was attacked on Wednesday at about 12.30pm - nearly 24 hours before she was found.
Ms Widdecombe, who was 78, was expected to appear on Channel 5's Matt Allwright show after 1pm.
WhatsApp messages between a producer from the show and Ms Widdecombe revealed she responded to a message confirming receipt of a a Zoom link at 12.19pm.
REMEMBERING ANN WIDDECOMBE:
A 12.48pm, she was asked to join the Zoom call, but did not respond to the message or later further attempts to contact her.
On Saturday, Reform UK leader Nigel Farage visited her Dartmoor home, which she named "Widdecombe's Rest".
His party's MPs were given 24-hour security following the Reform UK spokeswoman's death, paid for by Reform UK.
Mr Farage described her as "much more than just a politician" as he paid tribute to the former Tory Prison Minister.
He said: "Unlike modern politicians, Ann never needed notes. She never sought popularity for the sake of it, she stood up and fought what she believed in.
"I’ve come here today to lay this wreath on behalf of many millions around this country that admired her, loved her."
Politicians across the political spectrum, including Sir Keir Starmer, Kemi Badenoch and Ed Davey also paid tribute to Ms Widdecombe, who was first elected to parliament in 1987.
She also found fame outside of politics, appearing in Strictly Come Dancing and as runner-up on Celebrity Big Brother.
