After the MUDA chairman stepped down from his post on Wednesday, the BJP demanded that Karnataka Chief Minister Siddaramaiah also resign immediately as he is "deeply embroiled" in the land "scam". Mysuru Urban Development Authority (MUDA) chairman K Marigowda resigned from his post amid the row over alleged irregularities in allotment of sites to Siddaramaiah's wife Parvathi B M. "MUDA chairman has tendered his resignation... I call upon Siddaramaiah that if you have the slightest morality left in you, you should step down immediately. You should not wait for today's sunset," BJP national spokesperson and MP Sambit Patra said at a press conference here. He said Marigowda's resignation and Siddaramaiah's wife "offering" to return the MUDA sites allocated to her make it clear that the chief minister is "deeply involved in the scam from head to toe". "There is no doubt about it," Patra said. Earlier in the day, Marigowda submitted his resignation to the Urban Development Department .
