Ghana's former President, Flt Lt Jerry John Rawlings has issued a public message of congratulations to President-Elect, John Dramani Mahama.

"Following the successful conclusion of the 2012 Presidential and Parliamentary elections I extend warm and sincere congratulations to President-Elect John Dramani Mahama," the statement issued by his office said.

The statement called on President-Elect John Mahama to endeavour to restore and defend the ruling National Democratic Congress (NDC's) ideals of unity, stability, development, probity and accountability at all times, as he fulfills the mandate entrusted upon him by an expectant electorate.

"I urge the leading opposition party to respect the atmosphere of peace, which characterized the elections. If there are grievances over the results of the elections they should follow the appropriate channels and desist from creating an atmosphere that can potentially hurt the peace and stability in the country.

"Once again I commend all Ghanaians for ensuring that the electoral process was held in an atmosphere of serenity despite the challenges posed by the introduction of the voter verification equipment."
