He was appointed member of the Central Legislative Assembly in 1938 and Member of Council of States on 18 February 1939. He did not make many speeches, and was not an active participant in the colonial politics at the time.
William Birdwood had clearly stated that the Sikh prisoners kept in Rasina Hill after the Jaito Morcha and
Akali Movement should have been kept in custody. He wrote a letter congratulating Sir Sunder Singh Majithia and wished his success in the Akali Movement, though Sir Sobha Singh was against Sikhs (or Indians) demanding independence from the British Raj. This was following an incident where the
Delhi Police had cordoned a procession of Sikhs and trampled over two children. One of Sobha Singh's famous speeches was about a Sikh Gurdwaras and Religious Endowments Bill, which led him to become the brainchild of the
Delhi Sikh Gurdwara Management Committee. Most of his speeches were about Sikh rights, he also wished to create a separate Anand Marriage Act, but the British and Indian Nationalists both pressed him, hence he was on the Committee for the Hindu Law (Marriage) Bill. He also asked to increase the representation of Hindus in the Council of Sind, since Non-Muslims were not getting enough seats in the Sind province.
Bhagat Singh Court Case The story of Sir Sobha Singh's involvement in the Bhagat Singh issue was that first Sobha Singh came late and arrived when the division bell rang on the Trade Disputes Bill. Some friends of his were seated near the Ladies’ gallery and he looked towards them when the President announced the result of voting.
Misconception of Sobha Singh's role Bhagat Singh was hanged later, not for the bomb thrown in the Legislative Assembly, but for the murder of Saunders in
Lahore, in which Sobha Singh had no role to play. It was years after Sir Sobha Singh's death in 1997 that public attention was drawn to the incident by an article titled, 'Khushwant Singh's Father was Main Witness in Bhagat Singh's Trial' by Malwinder Jit Singh Waraich of
The Indian Express, which was erroneous and politically motivated in nature.
Great Bengal Famine Sir Sobha Singh said in parliament that the
Bengal famine of 1943 had exposed the constitutional defects inherent in the
Government of India Act 1935. By becoming autonomous units, the provincial Governments had become self-sufficient and insular in their outlook, regardless of the good of the country. While Lord Wavell had sent the army divisions and air force for relief work along the countryside, Sir Sobha Singh was tasked with improving railways and roads, which is why he was put on the Central Advisory Council for Railways, the Food Department for producing
Bajra,
Jowar,
Millet,
Rice and
Wheat instead of Jute plantations in the East Bengal region, the Committee for Agriculture and Forests so that he could help in the food scarcity situation and provide wood which was lacking in areas like Odisha's coastal area. He was also put on the Committee for the Labour Department to solve the rampant unemployment which was occurring in the area at the time. For his services he was proclaimed the "Feeder of Bengal" by
Rabindranath Tagore.
Interim Government of India Govind Ballabh Pant had created a team of people for Evacuee Property transactions after the Partition of India,
Dr. Zakir Husain, Sir Sobha Singh and Raghunandan Saran were all in the team to restore
Muslim properties in Delhi and give them to the migrant populations, mainly from
Sindh and from
West Punjab. They were able to restore most of the properties but the population influx had changed the overall demographics, to such an extent that there were not enough houses for the Sikhs and Hindus who arrived. He was given the position of chairman of the Delhi unit of the Swatantra Party in 1960, taking over from Sardar Bahadur Lal Singh in 1960. The manager (Hans Raj Pasricha) and Sir Sobha Singh did not get along well with each other, as the manager's ideology leaned to leftism, whereas Sir Sobha Singh's to the right. == Business career ==
