According to the news, who among the following were NOT involved in selecting the new symbol?

The search for a symbol for the Indian rupee began more than a year ago, when the government decided that the currency needed an identifiable symbol.
    After going through 3000 entries submitted in a national competition, a panel of bankers, officials and artists chose the new symbol. It is a mix of the Roman letter "R" and its Hindi equivalent in the ancient Devanagari script.
    Information minister Ambika Soni said the decision to have a symbol for the rupee is significant.
