New Delhi/IBNS: Congress leader Arvinder Singh Lovely Sunday resigned as the chief of the party's Delhi unit over its alliance with the Aam Aadmi Party (AAP).

Lovely said that several AAP ministers have been jailed over corruption charges, still, the Congress formed an alliance with them for the Lok Sabha elections amid opposition by party workers.

In a letter to Congress Chief Mallikarjun Kharge, he said that since he cannot protect the interests of the Delhi Congress workers, he sees no reason to continue as the chief of the unit.

"The Delhi Congress Unit was against an alliance with a party (AAP) which was formed on the sole basis of leveling false, fabricated and malafide corruption charges against the Congress. Despite that, the party made a decision to ally with the AAP in Delhi," he said.

Hinting at an internal rift, Lovely also alleged that several decisions taken by him as the Delhi Congress Chief were vetoed by the AICC General Secretary (Delhi In-charge).

"Since my appointment as DPCC President, the AICC General Secretary (Delhi In-charge) has not allowed me to make any senior appointments in the DPCC," he said.

He said the party gave Lok Sabha tickets to candidates who were "total strangers" to the Delhi Congress unit, referring to Udit Raj's candidature in North-west Delhi and Kanhaiya Kumar in Northeast Delhi.

Lovely was appointed the Delhi Congress President in August last year.

The Aam Aadmi Party and the Congress had agreed to a 4:3 seat-sharing formula for Delhi earlier this year to put up a joint fight in the upcoming Lok Sabha elections.
