Somdev Devvarman, too, was given a wild card in men's singles, thereby making it the largest tennis contingent ever fielded by India in Olympics.
It was learnt that the All India Tennis Association (AITA) has got a letter from ITF president Francesco Ricci Bitti stating that they have awarded wild cards to Sania and Rushmi for women's doubles event and Somdev for men's singles.
With their participation confirmed, India will now have seven tennis players competing in London.
Leander Paes, Mahesh Bhupathi, Rohan Bopanna, Visnu Vardhan were the other four selected by the AITA selection committee here last week.
