Discussed the prolonged farmers' agitation against farm laws and urged him to resolve the crisis urgently with the repeal of the laws and guarantee MSP, besides supporting Punjab in crop diversification.However, the politically significant meeting, which came days after Singh resigned as chief minister after accusing the Congress of humiliating him, raised speculation over his future plans ahead of the polls in Punjab with some political analysts viewing it as an indication that Singh may be seeking the support of the Bharatiya Janata Party (BJP).After the Singh-Shah meeting, Congress chief spokesperson Randeep Surjewala alleged that Amit Shah's residence has become the centre of anti-Dalit politics. In a series of tweets in Hindi, he said, "the arrogance of the those sitting in power has been hurt. Because if a Dalit is made the Chief Minister, then they ask who is making the decisions in the Congress." "The centre of anti-Dalit politics is nowhere else but Amit Shah's residence," he alleged.He also alleged that "Amit Shahji and Modiji are burning in the fire of vengeance...They want to take revenge on Punjab as they have so far failed to serve the interests of their capitalist friends with the black anti-farmer laws. BJP's anti-farmer conspiracy will not succeed. "Singh's meeting with Shah has added another dimension in politics in Punjab where no party is being seen as a clear favourite in the polls, expected to be held early next year. Amid speculation that the former chief minister may join hands with the BJP, a senior BJP leader said such a possibility cannot be ruled out.A lot will depend on whether the Centre makes a climbdown on the contentious farm laws, other sources said. If the Modi government works to resolve the farmers' issue then it will smoothen Singh's path to either join the BJP or support it, they said.Also Read: Punjab Congress crisis: Ajay Maken hits back at Kapil Sibal; says don’t denigrate party that gave you everythingWith the farmers' protests also seen to be affecting the BJP's prospects in western UP, the Modi government may intensify efforts to end the stir.
