Multiple reasons for Sidhu's resignation 

Chandigarh: Congress high command is undecided over Navjot Singh Sidhu's resignation to Punjab Pradesh Congress Committee chief post, sources said that party is unlikely to accept his resignation. 

Two cabinet ministers and party state general secretary has also resigned in support of Mr. Sidhu. With the resignation of two ministers, the crisis is deepening in the party. 

Sources in the party stated that there were multiple reasons for his resignation, including non considering him for the CM post after his betenoer Captain Amarinder Singh was step down from the CM post on September 18, 2021. 

Cricketer turned politician Navojot Singh was appointed as PPCC chief on July 18 despite stiff opposition from then Chief Minister Amarinder Singh. Though the party has appointed Sidhu nominee Charanjit Singh Channi as the new Chief Minister, his upset towards the party has raised the eyebrows of many in the party. 

Sources said that Mr. Sidhu was upset with the appointment of senior advocate A.P.S Deol as Advocate General. His dissidents, Rana Gurjit and Bharat Bhushan Ashu were inducted into Cabinet.

Sidhu was annoyed with the induction of former irrigation minister Rana Gurjit Singh into the Cabinet. Mr. Gurjit was removed from the Amarinder Singh Cabinet in 2018 following corruption charges. He was involved in the alleged allotment of a sand mining contract to his close aides. 

Rana's induction to the Cabinet does not go well in the party; opposing his induction to the cabinet, six Congress MLAs had written to Sidhu expressing their resentment, stating that Mr. Rana is yet to be resolved of the charges.

Another reason for Sidhu's upset with the party was the induction of Bharat Bhushan Ashu to the Cabinet, Ahsu has switched the side of Amarinder Singh when he later resigned to the CM post. However, Ahsu is also in close contact with Gandhi siblings. 

When he was minister in Amarinder Singh Cabinet, Mr. Sidhu ordered for enquiry against Bharat Bhushan Ashu regarding his nexus with a realtor. However, the enquiry was stopped following Sidhu’s resignation to the Cabinet. Subsequently, enquiry has been suspended following Ashu’s complaint. 

Both Akali Dal and Aam Aadmi Party made allegations against Ashu when he was the food and civil supplies minister in Amarinder Singh Cabinet, the same portfolio was given to him by Channi.

Sidhu has vehemently opposed for appointment of A.P.S Deol as Advocate General, because he was the Advocate for DGP Sumedh Singh Saini, who was charged for the killing of two Sikh protesters in Behbal Kalan in 2015, during Akali Dal and BJP government. 

Even sources also maintained that Mr. Sidhu was a strong contender for CM post, but party high command asked him to lead the party in coming Assembly elections, he was disturbed the with development after-party high command poured cold water for his desire to become CM.
