Nancy Norman will attempt to get back into Scottish Borders Council, ten years after first being elected.
The former church minister has been named as the Liberal Democrats candidate for the Tweeddale West by-election in October.
The ex-Independent councillor was elected to one of the two former Peebles wards in 2003 but failed to claim a seat in the revamped Tweeddale West seat in 2007.
She then lost the 2012 Tweeddale West election but has vowed to return more power to Peeblesshire if elected.
Mrs Norman said: “I am worried about power and services being taken away from the area, most recently exemplified by the closure of Peebles Sheriff Court.
“I am standing as a Liberal Democrat as I want to be part of a strong team that has, and will continue, to deliver for Tweeddale.”
Current Tweeddale West Lib-Dem councillor Catriona Bhatia added: “Nancy has a wealth of experience as a councillor, crucial for someone being elected mid-term.
“Her experience and her passion for the local area, means she would be a great asset.”
Jeremy Purvis, announced as a peer earlier this month, said: “Nancy will be known to many as a compassionate but also tenacious local spokesperson with unparalleled integrity.”
