The African National Congress (ANC) in Mangaung is threatening to subject its councillors in Mangaung to polygraph tests. 

This after some of them defied the party line and voted for Democratic Alliance (DA) Councillor Maryke Davies as the new Speaker of the Mangaung Metropolitan Municipality.

The majority ANC-led council saw power slip out of its hands as Davies was elected Speaker, notwithstanding that her party only has 26 seats compared to the ANC's 51 in the 101-seat council.

She received a resounding 53 votes out of 93 valid votes on the day.

The ANC in the province is said to be targeting councillors who have been expressing displeasure over the outcomes of the ANC's Free State conference held in January.
