Mr Elliott has said he will not seek re-election to the position at the annual general meeting, in just over three weeks time.
In a statement outlining his decision and the reasons behind it, he said some “obstruction and hostility” began immediately following his election as leader and has been “relentless” since then.
The party’s AGM is scheduled to take place on Saturday 31 March.
“It has been a great privilege for me to lead the Ulster Unionist Party. I have been given great support by the vast majority of party members, both elected and non-elected,” Mr Elliott said.
“I am also well aware that some people have not given me a fair opportunity at developing and progressing many initiatives,” he said.
“Some of this obstruction and hostility began immediately following my election as leader and has been relentless since then. However I accept that is part and parcel of politics.
