Thiruvananthapuram: CPI(M), despite being the coalition partner of Congress in the Lok Sabha, has reasons to worry over the entry of Congress leader Priyanka Gandhi in the electoral fray from the Wayanad Lok Sabha seat as it could hit the prospects of the ruling party .
Along with the Wayanad Lok Sabha seat, Palakkad and Chelakkara Assembly seats will also go to bypolls as sitting MLAs are elected to the Lok Sabha.
