Former Punjab chief minister Amarinder Singh met Union Home Minister Amit Shah at his residence here on Wednesday, raising speculation over his future in politics.

Later, he tweeted that he discussed the farmers' protest with the Union home minister and urged him to repeal the contentious farm laws. Amarinder's media adviser Ameen Thukral said too much was being read into the visit, reported ndtv.com.

Singh arrived in the national capital on Tuesday, days after he quit as the chief minister of Punjab.

The meeting assumes significance as Singh had not opened his cards but had claimed that he had not quit politics and would fight till the end.

The veteran Congress leader had also launched a scathing attack on his bete noire, Navjot Singh Sidhu, who was appointed as the party's Punjab unit president.

Sidhu quit as the Punjab Congress chief on Tuesday.

As regards his political future, Singh had said there were several options before him.

Sidhu had on Tuesday abruptly sent in his resignation from the post of Punjab Congress president, days after the party removed entrenched leader Amarinder Singh as chief minister following a tussle between the two.

Sidhu’s sudden decision not only intensified the problems of the ruling Congress in poll-bound Punjab, it also caused deep embarrassment to Rahul Gandhi and Priyanka Gandhi Vadra as they had taken a huge risk by bulldozing all hurdles to project him as the supreme leader in the state.

The majority of senior leaders in the high command structure had not been in favour of promoting Sidhu but Rahul and Priyanka appeared to have been swayed by his popularity in their effort to retain Punjab in the next election.

Sidhu wrote in his resignation letter: “The collapse of a man’s character stems from the compromise corner. I can never compromise on Punjab’s future and the agenda for the welfare of Punjab. Therefore, I hereby resign as the president of the Punjab Pradesh Congress Committee. I will continue to serve the Congress.”

He posted the letter on Twitter without clearance from the central leadership, sources said.

The sources said that while Sidhu was upset because he wanted to become chief minister after Amarinder’s exit, his anger boiled over when new chief minister Charanjit Singh Channi made appointments without his approval.

But the dominant sentiment in the party is hostile towards Sidhu with most leaders condemning his “immaturity” as “unpardonable betrayal”.

The sources claimed that even Rahul was livid.

While Amarinder asserted that Sidhu was not a “stable personality”, most other senior leaders said Sidhu should have considered the risks Rahul and Priyanka had taken for him. They believe the Congress should persist with the pro-Dalit narrative in the aftermath of Channi’s elevation by discarding Sidhu and immediately appointing someone else as the state unit chief. These leaders are of the opinion that dilly-dallying will further complicate the web that the party looks stuck in.

A senior leader told The Telegraph: “Sidhu is now raking up small issues without realising the overarching goal of winning the election. The main issue is that he feels the chief minister is not willing to be a puppet.
