I doubt on the than British Lord and Governors and Why Mr.Jawaharlal Nehru not called Ava Gandhi and Manu Gandhi in to politics to lead the Nation in future like he called and trained Indira Priya darshini also known as Indira Gandhi ?

Gandhiji shot dead - The Hindu (January 31, 1948)

Mahatma Gandhi, the Father of the Nation, was shot at 5-12 p.m. to-day and he died fifteen minutes later. Gandhiji left his room in Birla House for the prayer meeting a few minutes after the conclusion of his talk with Sardar Vallabhbhai Patel. He passed through the garden leaning on the shoulders of Ava Gandhi and Manu Gandhi, grand daughter-in-law and grand niece.
It is learnt that the name of the assassin is Nathuram Vinayak Godse (aged 36), a Mahratta. He described himself as the Editor of a daily paper called Hindu Rashtra published in Laxmipet, Poona.

 He wore khaki pants and tunic. There is no truth in the report that he attempted to commit suicide by putting a bullet into himself.

Why Mr.Jawaharlal Nehru not called Ava Gandhi and Manu Gandhi in to politics to lead the Nation in future like he called and trained Indira Priya darshini also known as Indira Gandhi is still deepen a doubt in my mind,also you will also will have the same view?
Including BJP till date why No one is initiating to Bring these people to India and in Press and media about their survival and other Knowledge to Indians. It is a need. 
while we knowledge about Indira Gandhi we must Know about the surviving family members of Mahatma Gandhiji is a Must is my view as a Indian.
what is the Necessary to Give importance to Nehru Family People in India by Indians in all these Days?

As a Indian after reading all matters about the death of Gandhiji whose Name is Mohandoss Karamchand Gandhi from Gujarat in India ,we gain or I got knowledge about the treatment of Gandhiji by British Government Officials in India of that time. On many places British Governors and Lord's said that Mahatma Gandhiji approaches using Non Violence methods blocked them from Punishing or imprisoning Gandhiji.they do not know how to punish Gandhiji is further added .
Till 1945 why British Government not initiated about Freedom to India? Suddenly on allied and Non allied in declared II World War from 1945 to 1949 ,in the Middle in 1945 what made British Government to release Freedom order to India?. Also I doubt on British Government, why Gandhiji Killed Brutally in 1948 before the end of II World War in 1949. Is their any Drama by British Government in the Killing of gandhiji or any Popular Politicians of that time who had relation with Lord Mountbatten  could have arranged this killing ? All these  possibilities  on doubt strikes in my view / opinion?why because why world leaders not raised any question about the survival of Family members of Gandhiji in India or in Indian Politics were not at all analyzed by strong Media like BBC,ABC,Reuters,and P T I.
Thanks.
