Sukhbir Singh Badal said Navjot Singh Sidhu has deceived his party in the hope of a "bright future".
Punjab Chief Minister Parkash Singh Badal today attacked former Rajya Sabha lawmaker Navjot Singh Sidhu, saying "opportunists" and "fugitive" leaders like him have no place in the state's politics and people will teach him a lesson like they taught Surjit Singh Barnala and Manpreet Singh Badal.
He said though Mr Sidhu, with whom Shiromani Akali Dal (SAD) has had a running feud, had deceived his party in the hope of a "bright future", people of the state would not forgive him and teach him a lesson for "treachery" because they have a strong dislike for people who deceive their parties.
"Opportunists and fugitive political leaders like Sidhu have no place in Punjab politics and people will teach him a befitting lesson," Mr Badal told a gathering.
The chief minister said, bereft of any ideologies, both these leaders (Surjit Singh Barnala and Manpreet Singh Badal), had back stabbed their mother parties and Mr Sidhu was not an exception.
He said that the Arvind Kejriwal-led Aam Aadmi Party (AAP) was proving to be a haven for all the "fugitives" and "unprincipled" politicians, who hardly have any base among people.
He said that the AAP was a band of opportunists and fugitives who have joined hands for looting the people of Punjab.
"These people don't have any ideological bonding but have joined hands in the false hope of assuming power in the state," Mr Badal added.
Making a scathing attack on state Congress chief Amarinder Singh, he said the Lok Sabha lawmaker from Amritsar has a proven anti-farmer track record.
Citing an example, he said the SAD-BJP alliance had been providing free power to farmers but during Mr Amarinder's tenure as chief minister, it was discontinued, putting enormous burden on them.
Mr Badal alleged that the state Congress chief was "part and parcel" of the conspiracy to rob Punjab's water by constructing the Sutlej-Yamuna Link canal.
"It is on record that Amarinder had welcomed the then Prime Minister Indira Gandhi to lay foundation stone of this canal," he added.
Lauding the centre's announcement to set up an All India Institute of Medical Sciences (AIIMS) in Bathinda, he said it would prove to be a boon for residents of Malwa region.
