Of the 13 ministries that deal with India's economy, changes took place only in three - steel and mines, corporate affairs, and railways, India's biggest employer.
Among the major changes, Salman Khursheed took over the law ministry from M. Veerappa Moily, who moved to corporate affairs; Dinesh Trivedi of the Trinamool Congress heads the railways; while Jayanthi Natarajan, the only Congress woman MP from Tamil Nadu, is the new environment minister.
She replaced the hyperactive Jairam Ramesh who was elevated as a cabinet minister in the ministry of rural development.
'Consideration of efficiency, of continuity and all elements were taken into account,' Manmohan Singh said of the changes made in his government.
He underlined that Jairam Ramesh had been rewarded for good work.
Besides Natarajan, the other new faces are V. Kishore Chandra Deo, Sudip Bandopadhyaya, Milind Deora, Jitendra Singh, Rajiv Shuila, Paban Singh Ghatowar and Charan Das Mahant.
Among those asked to go were DMK's Dayanidhi Maran, who put in his papers earlier after being linked to the spectrum scandal, and M.S. Gill, the sports minister when India hosted the corruption-hit Commonwealth Games.
