Chief Minister Arvind Kejriwal on Wednesday accused the Modi government of causing hindrances in Delhi's development and said he could prove wrongdoing by the Centre if its files were made available to him.Speaking at an event to mark the third anniversary of the AAP government, he said the Delhi government was struggling to get approval for its policies from Lt Governor Anil Baijal, an appointee of the Central government.Referring to the government files stuck with the Lt Governor, Kejriwal said the MLAs were forced to virtually camp at his residence whenever this happened.He added that the Shunglu committee, appointed by the Centre, failed to find any wrongdoing in the 440 government files of the Delhi government even after investigating them for months.In turn, he challenged the Modi government to submit its files to him."Show me your files for four days, and I will teach you a lesson," the Aam Aadmi Party leader said.He said 16 to 17 bills passed by the Delhi Assembly were pending with the central government.He accused the Lt Governor of delaying his government's flagship Mohalla Clinics as he kept sending the files back and forth for one and a half years.
