The Federal Government and labour unions yesterday opened negotiations to break the deadlock over scrapping of petrol subsidies, as swelling numbers of demonstrators took to the streets in a second day of protests across the country. A meeting brokered by the Senate leadership was held at the home of Senate President David Mark last night, attended by Secretary to the Government of the Federation Anyim Pius Anyim and Labour Minister Emeka Wogu from the government side. Labour leaders at the meeting were Trade Union Congress president Peter Esele, Nigeria Labour Congress president Abdulwaheed Omar, NLC vice president Issa Aremu and NLC acting secretary Owei Lakemfa. Also at the meeting were Senate President David Mark, deputy Senate Leader Abdul Ningi and other principal officers. The meeting ended at about 10.40pm, but the two sides failed to agree. Omar told journalists after the meeting that they had made some progress because for labour to agree to talks, it means they had shifted grounds. But he said no agreement was reached and so the strike and protests would go on.
