In 2023, the House of Lords commissioner for standards found that Ranger bullied and harassed a journalist following a Diwali event in Parliament.

After further revelations of derogatory comments about Pakistanis and Sikhs, Ranger's CBE appointment was revoked by the Honours Forfeiture Committee in 2024.

[2][3] Shortly after his birth, the family moved to Patiala in Indian Punjab as refugees of the partition, and Ranger was raised with seven siblings by his widowed mother.

[4] Ranger took up odd jobs after migrating to the United Kingdom, including working as a KFC chef in Norbury, south London, before being promoted to district manager.

[10] In 2018, alongside MP Zac Goldsmith, Ranger was appointed a co-chairman of Conservative Friends of India, linking the party with the British-Indian community and supporting stronger India–United Kingdom relations.

His words were found to have had the effect of "violating the claimant's dignity and creating an intimidating, hostile, degrading, humiliating and offensive environment for her".

[20] In 2022, the House of Lords commissioner for standards initiated an investigation into Ranger following a complaint by Poonam Joshi, a female journalist who accused him of bullying and harassment.

[21] The commissioner's report, published in June 2023, found that Ranger bullied and harassed Joshi through a series of tweets and WhatsApp messages.

He apologised to Joshi, and promised to undertake social-media training and re-attend a seminar on the parliamentary behaviour code, in lieu of being suspended from Parliament.
