Bangalore, May 2 (IANS) Karnataka Chief Minister B.S. Yeddyurappa Monday said many files that would expose "irregularities" during the Congress and Janata Dal-Secular rule in the state were missing from the secretariat.

 
 Several files pertaining to the period when JD-S leader H.D. Deve Gowda and his son H.D. Kumaraswamy were chief ministers have been moved to Gowda’s house, the chief minister told reporters here.
 
 Gowda was chief minister in 1994-96 and Kumaraswamy headed the JD-S-BJP coalition in 2006-2008 when Yeddyurappa was his deputy.
 
 The Congress ruled the state in 1999-2004.
 
 "We have identified officials involved in this and will soon serve them notice (seeking explanation)," Yeddyurappa, who became BJP's first chief minister in the state in 2008, said.
 
 He reiterated that illegal mining thrived under Congress and JD-S rule in Karnataka and not after the BJP came to power.
