Aam Aadmi Party (AAP) leader Akshay Marathe has challenged the Lieutenant Governor to face investigation over Delhi's excise policy row. Mr Marathe pointed out the BJP often says the AAP shouldn't be scared of an investigation, so why shouldn't the Lieutenant Governor face a probe, what is he scared of? The Arvind Kejriwal government and the ruling BJP in the centre are at war again, with Mr Kejriwal's deputy Manish Sisodia facing a probe over alleged corruption in changing Delhi's excise policy.
