"Mrs. Vadra's statement yesterday (Sunday) on Smriti Irani, denying her existence by asking a question 'who', displays arrogance at its worst," Jaitley said in his blog.
Asked about Irani's prospects in the election against Rahul Gandhi from Amethi, Priyanka had last week asked who was Smriti Irani.
Jaitley recalled that in the 1967 Lok Sabha election, George Fernandes was pitted against then strongman in Mumbai politics S.K. Patil and had managed to defeat him.
"Mrs. Vadra's query on Smriti Irani questioning her existence reminds me of the Patil-George confrontation," he said.
