The BJP on Friday attacked the Delhi government after the Centre returned the proposed bill to hike salaries of MLAs and demanded its withdrawal."Now that the central government has returned the Aam Aadmi Party (AAP) government's Bill to raise the salaries of MLAs and ministers. It will be better if (Delhi Chief Minister) Arvind Kejriwal government withdraws it," Delhi Bharatiya Janata Party President Manoj Tiwari said in a statement.Tiwari alleged that Kejriwal government in its "ego spree wrongly passed the Bill raising the salaries of its MLAs last year despite strong protest by people of Delhi".The BJP leader's remarks came after the Ministry of Home Affairs (MHA) returned a bill to Delhi government and sought clarification on suggesting a hike of nearly 400 per cent in the existing salaries and perks for AAP MLAs."Centre has rightly asked for justification for the proposed 400 per cent salary hike for MLAs. It will be better if Kejriwal government concentrates on Public Welfare Work," Tiwari, who is also a BJP MP from northeast Delhi added.
