Besides National Museum, post of directors are lying vacant in National Gallery of Modern Art at Mumbai and Bengaluru, Indian Museum (Kolkata) and Salarjung Museum (Hyderabad), Culture Minister Mahesh Sharma said in a written reply.
"The posts are lying vacant mainly because of non-availability of suitable candidates and litigation," he said.
The selection process "in conjunction with Union Public Service Commission (UPSC) and Department of Personnel and Training (DoPT)" is already "underway" for the existing vacancies, the minister said.
