He funded the current PM from being a no name local politician all the way to prime minister ( an ascent which included brutal racial killings of Muslims in Gujarat).
And since his reaching PM status, Modi's government has allowed one shady businesses practice after another to be carried out by Ambani's many companies, ultimately culminating in the passing of the three farming ordinances which would give Ambani's companies significant freedom to fixing prices of crops. This model has already been tested by Modi and Ambani in Gujarat, where Ambani's companies now own the farmland while local farmers immigrate of out state to find labor jobs...
