President George Weah said the accord signed by 26 political parties shows the country's commitment to national stability during the polls.

“History has taught us that the risk of post-conflict countries to regress to war is extremely high. By any account, therefore, Liberia is a post-conflict success story,” Mr Weah said.

The pact obliges signatories and their supporters to uphold peaceful elections and resort to constitutional means if they are dissatisfied with the electoral process and outcomes.

Members of observer missions from the African Union, the European Union and other diplomats witnessed the signing of the accord.

The elections are expected to be hotly contested with the incumbent facing strong challenges from former vice-president Joseph Boakai of the former ruling Unity Party and Alexander Cummings of the Collaborating Political Parties.
