Citing a proverb, Yadav said, "With empty stomach, people have now understood that the BJP does not mean business."
Asking the BJP to restrain its leaders from making "ridiculous" comments, he said, "The BJP should learn to face defeats or else they will not be able to digest the outcome of the 2019 Lok Sabha elections in which the opposition will stage a comeback."
"Chief Minister Yogi Adityanath says he does not celebrate Eid as he is a Hindu. The BJP charges us with practising Muslim appeasement. Modi has just visited Indonesia and Malaysia during the month of Ramzan. Is it an attempt towards 'international appeasement' of the Muslims," asked Akhilesh.
Adityanath had reportedly said that he is a Hindu and does not celebrate Eid, drawing sharp criticism from the opposition.
Prime Minister Narendra Modi was for the first time on an official visit to Indonesia - the world's most populous Muslim-majority nation - last month. He has visited Singapore twice and Malaysia once in 2015.
Modi had also visited Indonesia's grand Istiqlal Mosque, the largest in southeast Asia, with President Joko Widodo.
Indonesia is not only the world's most populous Muslim country, followed by India, but the third largest democracy. Hindus comprise two per cent of Indonesia's population and form close to a 90 per cent majority on the island of Bali.
