After 10 hours of voting, polls have officially closed in Tanzania’s election where 15 candidates are running for the presidency including the incumbent John Magufuli.

More than 85,000 polling centres across the country closed at exactly 16:00 local time (13:00 GMT).

The authorities say the process was largely peaceful, despite social media restrictions and claims of irregularities.

Two main opposition parties Chadema and ACT-Wazalendo have claimed there was widespread ballot tampering.

In a tweet, Tundu Lissu, Chadema’s presidential candidate said they had received reports indicating widespread irregularities.

He also alleged that opposition polling agents were prevented from accessing some polling stations.

The National Electoral Commission chairperson Semistocles Kaijage denied the claims, saying they are unfounded.

In the island of Zanzibar, polling passed off peacefully a day after violent clashes, in which ACT-Wazalendo claimed 10 people were killed. Police, however, denied the claims but added that 40 people had been arrested in the region.
