The 29-year-old (pictured) made 285 appearances for the Saints – and won the FA Trophy - after re-joining in the summer of 2016 after spending the previous season with Corby Town.

The right-back started his career as a trainee at Leicester City before spells at Brackley and Rugby Town.

He later joined Stamford, where he was a consistent performer in the Daniels’ side before moving to Steel Park.

Boston boss Paul Cox told https://www.bostonunited.co.uk: "Ellis has been a consistent performer at this level for a number of years, having experience of numerous play-off campaigns and picking up a winner's medal at Wembley.

"I feel that he will bring good experience and a knowhow and really compliment his new team-mates."

Cox has also swooped for midfielder Ben Pollock from another league rival, Hereford FC.

The 24-year-old had signed for the Bulls in October 2019 following a successful trial period.

He is the son of Jamie Pollock, who played in the Premier League for Manchester City, Middlesbrough and Bolton Wanderers.

A former Newcastle United youngster and whose brother, Mattie plays for Grimsby Town, he signed a professional contract with Hartlepool United in 2016 and made his debut in a 1-0 defeat to Sunderland in the EFL Trophy.

He later played for Dunston UTS in the Ebac Northern League First Division before signing for Northern League Second Division outfit Billingham Synthonia in July 2018.

Also joining the Pilgrims is central midfielder Lebrun Mbeka from former league rivals, Guiseley AFC, who were relegated at the end of last season.

The 25-year-old, who is also capable of playing at centre-half, arrives at the Jakemans Community Stadium having been a mainstay of the Guiseley side since joining from Tadcaster Albion in September 2020.

Born in Congo, Mbeka has featured extensively across Yorkshire in recent seasons, including spells with Sheffield FC and Ossett United.
