New Delhi, January 28 The Budget session of Parliament is expected to be off to a stormy start on Friday with 18 Opposition parties, including Shiromani Akali Dal, AAP and 16 led by Congress, set to boycott the President’s Address to both Houses to express solidarity with the protesting farmers. The 16 parties, announcing their decision to boycott the President’s speech, accused the government of showing “insensitivity” to the demands of protesters. They sought repeal of farm laws in a joint statement and demanded an impartial investigation into the Centre’s “nefarious role in orchestrating the Republic Day events in the Capital” while accusing the government of attempting to discredit the farmers’ movement.
