Tens of millions of public sector workers have gone on a day-long strike across India, protesting against Prime Minister Narendra Modi's economic policies, particularly his plans to push for greater privatisation. Thousands of state-run banks, government offices and factories were closed on Friday, and public transport disrupted, in the strike called by 10 trade unions. "This strike is against the central government, this strike is for the cause of the working people," said Ramen Pandey, of the Indian National Trade Union Congress. "Our strike will be 100 percent successful ... we will prove that this strike is the world's largest ever." Union officials said about 180 million workers, including state bank employees, school teachers, postal workers, miners and construction workers, were participating, but the figure could not be independently verified.
