In a statement here, she said while BJP was indulging in "gimmickry", the Centre was "inactive" and the Governor was "silent".
"The Centre should stop making statements and instead take proper constitutional and legal action against the SP government," she said.
"It is a known fact that encroachment on government land and those staging dharna had government patronisation, otherwise it would not have remained silent for two years. Laxity on the part of the Centre and its intelligence agencies is no less," the BSP supremo claimed.
She said BJP was only making statements, proving it has joined hands with SP against BSP in view of Assembly elections in 2017.
