The election of a new national executive of the Nigeria Labour Congress (NLC) has ended in chaos in Abuja.

Aggrieved delegates were caught on Channels Television camera smashing and emptying ballot boxes with ballot papers flying on the floor of the International Conference Centre.

The workers alleged that the ballot papers were designed to favour one of the candidates vying for the President of the union.

Over 3,000 delegates commenced voting on Thursday as the General Secretary of National Union of Electricity Employees, Joe Ajaero, and the President of the Medical and Health Workers Union of Nigeria, Wabba Ayuba, presented themselves for election to replace Abdulwaheed Omar.

The President of NUPENG, Igwe Achese, had withdrawn from the race for Ajaero.

The NLC was formed by Nigerian workers in 1978 and has successfully conducted 10 delegates conferences.
