Bahujan Samaj Party (BSP) supremo Mayawati on Tuesday dubbed the ruling Bharatiya Janata Party (BJP) at the Centre as anti-Ambedkar and anti-Constitution.Addressing a gathering after paying floral tributes to Dr Bhimrao Ambedkar, popularly known as Babasaheb, on his death anniversary at the local Ambedkar Park here, Mayawati criticised "political parties for creating confusions about Babasaheb"."They (political parties) create rift between the Dalits and backward classes, whereas the fact is that it was under the BSP rule that these sections of society got their rights in true sense," she said.Training guns on the Rashtriya Swyamsevak Sangh (RSS) and the BJP, the BSP chief said: "These people do not like the Constitution... They want to change it. So, you need to guard against it."Ambedkar's Constitution accords equal status to all castes and religions, but the BJP is trying to impose the agenda of Hindutva on the country."She stressed that if Muslims are safe in the country today, it is because of Babasaheb."It was only after the 'master key' of Uttar Pradesh came in the hands of the Dalits that emancipation of backward classes and the Dalits could be possible, much against the wishes of the BJP and the Congress," Mayawati said.The BJP withdrew support to the V.P. Singh government on the issue of reservation, which is a proof that this party is anti-Dalit, anti-backward classes and anti-minorities, she said.Also, since the BJP does not want to give due honour and respect to Babasaheb, they chose December 6 -- the death anniversary of Dr Ambedkar -- to demolish the Babri Masjid in Ayodhya, the BSP chief alleged.
