Manmohan Singh, the former Prime Minister of India, faced financial difficulties during his time studying at Cambridge University in the mid-1950s, according to his daughter Daman Singh's book "Strictly Personal: Manmohan and Gursharan". The book details how Singh, who was on a scholarship, often had to skip meals or live on a sixpence bar of Cadbury's chocolate to make ends meet. The book also offers insights into Singh's personal life, including his fondness for singing, his quirky sense of humor, and his habit of giving nicknames to people. Daman Singh describes her father as a man who was careful with money, had a good sense of humor, and was a loving husband and father.
