In a fresh attack on the AAP-led Delhi government, the BJP on Tuesday said `sharab` (liquor) and `shiksha` (education) scams had become the "twin towers of corruption" in the Delhi government and the Arvind Kejriwal dispensation was gradually building more floors.

The BJP leaders also alleged that the Delhi government escalated the cost of building classrooms multiple times and projected several schools toilets as classrooms to justify the "bloated" costs.
