Condemning the ordinance authorising expenditure in Uttarakhand from Friday, the Congress on Friday termed it a "sinister conspiracy" by the Centre to obstruct and annul implementation of public welfare schemes and programmes of the previous government.President Pranab Mukherjee on Friday gave his assent to the ordinance authorising expenditure beyond April 1 in Uttarakhand which is under central rule.The union government on Wednesday approved the ordinance to authorise government expenditure in Uttarakhand from April 1 in view of President's Rule in the hill state."The Uttarakhand assembly had constitutionally passed the Appropriation Bill reflecting people's aspirations. This ordinance is nothing but Narendra Modi government's sinister conspiracy to obstruct and annul implementation of public welfare schemes and programmes, funds for which were allotted in the budget," said Congress spokesperson Randeep Singh Surjewala."The Congress party condemns the legislative dishonesty of the BJP government to deny genuine developmental aspirations of people of Uttarakhand by first proroguing parliament and then following the ordinance route to perpetuate illegalities," he added.
