Switching parties in commonplace in democracies when poll season is on and this is what happened in West Bengal as well.
Arjun Singh, lawmaker from Bhatpara Assembly seat, switched sides in New Delhi this afternoon.
The latest switching by Arjun Singh also leaves Chief Minister and Trinamool supremo Mamata Banerjee lose as a influential legislator to the BJP.
Arjun Singh wanted the ticket to the Barrackpore Lok Sabha seat and made no secret of his aspiration.
He is on record saying people of Barrackpore were not happy with sitting lawmaker Dinesh Trivedi. But Mr Trivedi has been renominated.
Arjun Singh did not hide his disappointment and only last night he flew to Delhi and showed up at the BJP headquarter.
The BJP had has announced a major joining from Trinamool and Arjun Singh did nothing to stem the speculation.
