Lucknow, May 20 (IANS): Rebel Congress MLA Aditi Singh has caused further embarrassment to the Congress in Uttar Pradesh with a series of tweets slamming the party on the controversy over buses.

Singh, who has been working against the party line for almost six months now, has termed the bus issue as a 'crude joke'.

"If buses were available, why were they not deployed in Punjab, Rajasthan and Maharashtra," she asked.

She termed the entire issue as petty politics and said that the list of buses included 297 buses which were unfit to travel, while 98 autos, ambulances and 68 vehicles did not have documents.

She further said that why did the Congress not deploy buses to send thousands of students stranded in Kota (Rajasthan) to their homes in Uttar Pradesh.

"It was Yogi Adityanath who sent buses to Kota to bring back these students," she tweeted.

Singh, the Congress legislator form Rae Bareli, has been constantly defying the party line. She attended the special Assembly session last year when the Congress announced that it would boycott the same.

She has also been praising the BJP and its leaders on social media, causing embarrassment to the party.
