Minister’s visit to new post office spoiled by protests.
Minister of Railways and Communications Ashwini Vaishnaw’s visit to a new post office in Bengaluru was marred by protests from supporters of local MLA N A Haris. The protesters alleged that the MLA was not invited to the function and his name was not printed on the invitation. They blocked a portion of the road and raised slogans in support of Haris.
A postal official said that the MLA had been invited to the function, but he was upset that he had been invited late. The official also said that only the minister’s name was printed on the invitation, and the names of the MP and other top officials were not printed.
The protest forced Vaishnaw to leave the venue immediately. BJP workers who were waiting to meet the minister were disappointed with the behavior of the Congress workers.
