United Oil & Gas Plc announced that Jonathan Leather has notified the Board of his intention to step down as Chief Operating Officer ('COO') and Executive Director as of 31 August. Whist Jonathan will step back from day-to-day operational activity, given the status of the Jamaica farmout process he will continue to provide support to the Company on a consultancy basis. The Company has commenced a search process to identify a new COO and with effect from September, Jonathan's non-Jamaican related responsibilities will be distributed amongst members of the management team in Dublin and Egypt.
