Social composition of Indian cabinets

Some fascinating data in a recent Livemint piece (h/t Milan Vaishnav):
“According to the political scientists, Christophe Jaffrelot and Gilles Verniers, OBCs have a share of around 20% among elected MPs in the Lok Sabha . While this figure is much more than the share of SCs, it still falls short of a proportionate share given the fact that OBCs have a population share of around 40% in India’s population. The dominance of upper castes and OBCs in Indian Union cabinets has been stark since the early days of the Indian republic, as an earlier Plain Facts column showed. The already skewed balance gets even worse when the BJP comes to power, as can be seen in the figures for 1999 and 2014.”
