Hitting back at Rahul Gandhi for using foul language against Prime Minister Narendra Modi, Uttar Pradesh government spokesperson Sidharth Nath Singh Tuesday said the Congress president has graduated from being a shehzada (prince) to "an emperor of lies".

Alleging that the Congress chief was misleading people, which will be of no use, the senior UP minister said Gandhi needs to come out with details to substantiate his claims about the then UPA government's decisions on the Rafale deal. "The shehzada has now graduated and become a shehenshah (emperor)... Rahul Gandhi has become an emperor of lies... I am saying this as he had in Amethi yesterday presented a story which is totally a lie," Singh said.
