Singh said that he was "deeply shocked" when Kejriwal led AAP "unceremoniously and undemocratically removed an honest Sukhpal Singh Khaira from the post of LoP".

Punjab MLA Baldev Singh on Wesdesday resigned from the Aam Aadmi Party (AAP) citing party chief and Delhi Chief Minister Arvind Kejriwal's "dictatorial, arrogant and autocratic style of functioning".

Baldev Singh is a close aide of Punjab MLA Sukhpal Singh Khaira.

Khaira had also resigned from the AAP earlier this month, citing Kejriwal's "dictatorial" leadership.

He said the party "totally deviated" from the ideology and principles on which it was formed after the Anna Hazare movement.

Baldev Singh said that he was "deeply shocked" when Kejriwal led AAP "unceremoniously and undemocratically removed an honest Sukhpal Singh Khaira from the post of LoP, without taking Punjab MLA’s into confidence".

In November last year, Sukhpal Khaira, along with Kanwar Sandhu, was suspended from AAP for indulging in "anti-party" activities. In July 2018, he was removed as Leader of Opposition (LoP) in Punjab Assembly after he criticised Arvind Kejriwal for tendering his apology to Akali Dal leader Bikram Singh Majithia.

"Your meek apology to the drug tainted former Minister Bikram Singh Majithia further revealed your double standards in politics," Singh wrote in his resignation letter to Kejriwal.

Singh lashed out at Kejriwal for "flirting with the Congress" and called it as "another example of sheer political opportunism".
