NEW DELHI/MUMBAI: Congress national spokesperson

, who was miffed at the reinstatement of some party workers who had misbehaved with her during a press conference in

Mathura

a few days ago, resigned from the party on Friday.

Hours after quitting Congress, Priyanka Chaturvedi joined Shiv Sena in the presence of party president Uddhav Thackeray.

"I am thankful to Uddhavji for giving me respect and welcoming me into the party," Priyanka Chaturvedi said after joining Shiv Sena.

"It is not true that I quit the Congress after being denied Lok Sabha ticket," Chaturvedi said in response to a query while addressing a press conference in Mumbai after joining Shiv Sena.

Welcoming her into party fold, Thackeray said that Shiv Sena workers have got a "good sister" in Chaturvedi.

Sharing her resignation letter on

, Chaturvedi said that she felt "overwhelmed and grateful" by the support she received in the past three days.

Chaturvedi in her resignation letter said, "In last few weeks, certain things have convinced me that my services are not valued in the organisation and that I have reached the end of the road. At the same time I also feel that more time I spend in the organisation will be at the cost of my own self-respect and dignity."

Calling out Congress' stance on safety and empowerment of women, Chaturvedi said that the values promoted by the party are not reflected in the action of some of its members.

She further extended her good wishes to the party and thanked her mentors for supporting a "rank outsider like me into the system".

Former Congress spokesperson also changed her bio on Twitter where she had made a clear mention earlier about the posts she held in the party.

The development comes two days after Chaturvedi had alleged that partymen, who had "misbehaved" and "threatened" her, were being let off.

She lashed out at the party in public and accused it of giving preference to "lumpen goons" over those who had given their "sweat and blood" to the Congress.

Chaturvedi had tweeted that it was unfortunate and saddening that those who threatened her have gotten away without even "a rap on their knuckles".

The

Congress had suspended some workers for misbehaving with Chaturvedi during a press conference in Mathura a few days ago.

But, on Monday, the party issued a communication in which it rescinded all actions taken earlier against such workers who "misbehaved" with Chaturvedi in Mathura.
