Opposition coalition celebrates igp idris retirement

I think there may be some confusion here.

The Inspector-General of Police (IGP) in Nigeria is not named Idris, but rather Mohammed Adamu. He has not retired.

However, if you're referring to Ibrahim Idris, who was the Inspector-General of Police from November 2016 to January 2019, it's possible that an opposition coalition may have celebrated his retirement.

Could you provide more context or clarify which Idris you're referring to?
