“From 1951 to 1967 he remained the general secretary of Bharatiya Janshangh (sic). He got the responsibility as President in 1968. Suddenly he was murdered. Only the party, Bharatiya Janata Party, developed by him became the political alternative.” (emphasis added)
In the original Hindi, which the e-book also contains, that last sentence sounds even more blatant: उनके द्वारा विकसित किया गया दल, “भारतीय जनता पार्टी” ही देश में राजनैतिक विकल्प बना (‘Unke dvara viksit kiya gaya dal, ‘Bharatiya Janata Party’, hi desh mein rajnaithik vikalp bana’). This line is more accurately translated as: “The party that he helped develop – the BJP – became the only political alternative in the country.”
