Trinity were beaten on penalties in the play-off semi-final at Bamber Bridge and are hopeful of going a step better next season.
"I’m delighted to commit for next season,” said Bishop. "Obviously, it’s taken a bit longer than would have been ideal, but there have been circumstances beyond our control that have affected things.

"While we are not going to be able to compete financially with a lot of the clubs, I believe we will be more than competitive again.
"I cannot understate the achievement of finishing fourth last season. However, next season is a blank canvas and last year’s league position counts for nothing."
