Independent councillor Sam Adeniji rejoined the Conservative Group on Lewes District Council after he left the party earlier this year.
His return was welcomed by leader of Lewes District Council Rob Blackman this week.
Cllr Adeniji is a district councillor for Seaford South and a Seaford town councillor.
Cllr Blackman said: “It’s great to have Sam back in the fold. He has always supported the group at the district council level and I’m glad to have him back on board.”
Cllr Sam Adeniji added: “A local issue developed that forced me to make a decision to leave the Conservative Group.
“Fortunately that has now been resolved but I have made no secret of my values and I am glad to be part of the team again.
“I remain committed to working hard for the people of Seaford.”
Cllr Adeniji was elected to the district council in May 2011 but left the Conservatives in April 2014, citing local issues.
He rejoined the Conservative Party and was readopted by the Conservative Group on June 23.
Cllr Adeniji left the Conservative Group as a result of the Conservative controlled Seaford Town Council increasing the precept, the resignation of six town councillors and the by-elections which resulted.
He said there was a lack of support from Conservatives about issues in the town such as campaigning for better health services. Cllr Adeniji added he had used his own money to pay for a hall to hold a meeting about the provision of health services in the town.
