The Centre has asked all states and Union Territories to tighten security during Tuesday’s ‘Bharat Bandh’ called by the farmers unions and supported by opposition parties, while asserting that peace and tranquillity must be maintained on that day, officials said. In a countrywide advisory, the Union Home Ministry also said the state governments and UT administrations must ensure that the COVID-19 guidelines issued with regard to health and social distancing are strictly followed. The states and UTs were told that peace and tranquillity must be maintained during the ‘Bharat Bandh’ and precautionary measures taken so that no untoward incident takes place anywhere in the country, a home ministry official said on Monday. The ‘Bharat Bandh’ has been called by the farmers unions who have been protesting the three farm laws enacted in the Monsoon Session of Parliament. Major political parties, such as the Congress, NCP, DMK, SP, TRS and Left, on Sunday came out in strong support of the bandh. Thousands of farmers, mostly from Punjab, Haryana and Uttar Pradesh, are protesting at various border points of Delhi against the new farm laws.
