Harris comes in to replace Cam Norrie as the 29-year-old continues his recover from injury, while Patten will take the place of Joe Salisbury.

They join a strong line-up with current US Open semi-finalist Jack Draper, last year’s Davis Cup hero Dan Evans and former world No.1 and Grand Slam champion Neal Skupski.

Harris was a hitting partner for the team at last year’s Finals but for both players, this is the first time they’ve been part of squad and they could be set to achieve LTA Colour Holder status should they play across any of the three ties.

Captain and LTA Head of Men's Tennis Smith said: "This is a very tough group with last year's semi-finalists and former champions in Argentina and Canada.

"We believe in our ability however and I'm delighted that Jack, Dan and Neal who played such a key role in helping us qualify last year are back again this year along with both Billy and Henry joining us for the first time off the back of some very strong results they had this summer,”

Great Britain will begin their Davis Cup campaign on Wednesday 11 September up against Finland, before tough ties against Argentina (Friday 13) and Canada (Sunday 15).

Tickets are still available from as little as £5 for under 18s and £10 for adults.
