For all the global chorus around the farmers' movement, the man at its centre seems oblivious of the celebrity support the farm stir has been getting. Farmers' leader Rakesh Tikait has welcomed the support from international artistes and activists, including pop icon Rihanna, climate activist Greta Thunberg and former adult star Mia Khalifa, but acknowledged he does not know them. "Who are these foreign artistes?", Tikait sought to know while talking to media at Ghazipur border om Thursday. "They may have supported us, but I don't know them." "If some foreigner is supporting the movement, then what is the problem. They are not giving us or taking anything away from us," he said.
