ANSWER: Justice Virendra Singh
Explanation:
SC on 16th December 2015 appointed retired judge Justice Virendra Singh as the Lokayukta of UP. A lokayukta is a anti corruption ombudsman. Bench of Justice Ranjan Gogoi and NV Ramana gave approval for the appointment. This is the first time SC has exercised powers to appoint a Lokayukta after orders that a person must be appointed for the position. Current Lokayukta Justice NK Mehrotra has been given multiple extensions before this.
