A speedy recovery has been wished upon Neil Somerville, the recently-appointed MLA for Fermanagh and South Tyrone, who has taken a leave of absence from his Assembly duties.
The former councillor had been picked in June to replace Tom Elliott after he was elected to Westminster as an MP, following a selection process marred by confusion.
He remains a member of the UUP.
On Tuesday, the party issued a statement which said he is “off work with stress and wellbeing issues”
It added that the party “both locally and at leadership level, is fully committed to doing what it can to support Neil”.
Fellow Fermanagh and South Tyrone unionist, DUP MLA Lord Morrow said: “It is with sadness that I learned today that Neil Somerville is unwell.
“I’d take this opportunity to wish him a full and speedy recovery and trust that very soon he’ll be well enough to return to his duties as an MLA.”
