"BJP is unreliable as it did not fulfil its promise of building Ram temple despite its resolutions in this regard. It had no intention of doing so and had only wanted to let it remain an issue," Yadav said.
He was speaking at a function organised to mark the birth anniversary of socialist leader and former Bihar chief minister Karpoori Thakur here.
Even when Atal Bihari Vajpayee became the prime minister and Kalyan Singh chief minister in Uttar Pradesh they did nothing for temple construction, Yadav said.
"Now the matter is in the court and all should await its verdict," he said.
Attacking BJP, Yadav said that its leaders are followers of Hitler's propaganda minister Goebbels who used to say that 100 lies turn true, and their prime ministerial candidate Narendra Modi is also following him.
