Union Minister and firebrand BJP leader Smriti Irani has made a big attack on Delhi Chief Minister Arvind Kejriwal and his Aam Aadmi Party for insulting Prime Minister Narendra Modi’s 100-yar-old mother. Addressing a press conference in the national capital, Irani said that the Gujarat unit of the Aam Aadmi Party insulted the 100-year-old mother of the Prime Minister just for cheap politics ahead of the assembly elections in Gujarat.
