Welsh Labour has expelled a Cardiff councillor following a three-year investigation which found he sexually harassed a teenager.
Keith Jones was suspended in 2022 after an official complaint was made but no details of the allegations have been released by the party.
BBC Wales has now learned that the investigation related to an incident where Jones was alleged to have inappropriately touched a young party member who was 17 at the time.
Jones said he had been "instructed by the Labour Party" there would be "legal consequences" if he spoke about the incident.
Welsh Labour said Jones was investigated in line with their rules and procedures and "action will always be taken if party members or elected representatives are found to have breached the high standards we expect".
