Ranger was born in July 1947 in Gujranwala, located north of Lahore in Pakistan. Since the family had migrated to the Indian state of Punjab during the partition in 1947, Ranger enrolled into the Modern School in Patiala.
After the completion of his school education, Ranger went to Mohindra College, and then obtained a BA degree from the Government College in Chandigarh. He arrived in the UK to study Law in May 1971.
Ranger started the Sun Mark group in 1987 with just PS2 capital. Today, the company has operations in over 120 countries.
He is also the chairman of the British Sikh Association that earlier this year signed a memorandum with the Hashoo Group of Pakistan to develop infrastructure along the Kartarpur corridor.
Ranger was appointed as the joint chairman of the Conservative Friends of India in 2018, with British lawmaker Zac Goldsmith, a group affiliated to the Conservative Party which aims to build stronger links between the Party, the British Indian community and India.
