Tanzania’s President John Magufuli has promised to work with his rivals after a landslide victory in an election marred by widespread irregularities according to the United States and Britain.

“I will be the servant of all Tanzanians. I would like to thank my fellow presidential contestants for participating,” Magufuli said at a function in the capital Dodoma where he formally accepted the results.

The opposition has called for on Monday to protest against the poll’s results.

According to results announced by the country’s poll body on Friday, Magufuli secured 84% of the vote against his leading opponent Tindu Lissu’s 13%.

On Saturday Lissu’s CHADEMA party and another opposition party, ACT-Wazalendo rejected the results, called for protests, and demanded a fresh poll be held.

The United States has said it was concerned about reports showing “systematic interference in the democratic process”.

Nicknamed the “Bulldozer”, President John Pombe Magufuli is praised by some for pushing through big-impact infrastructure projects and a sweeping anti-corruption campaign.
