The Imo State governor unveiled the post during the swearing-in of 27 other new commissioners for Imo State.
But his sister Ogechi Ololo later rubbished initial reports stating she would also be in charge of “couples’ fulfilment” – saying it was actually “purpose fulfilment”.
Either way, the announcement has been met with derision on social media.
Many questioned the need for such a role, and wondered what it would entail.
It also comes hot on the heels of other unusual decisions made by the governor in recent times.
Mr Okorocha raised eyebrows across the continent in October after he unveiled a statue dedicated to South African President Jacob Zuma – a man who has no apparent links to the south-eastern state.
This is pure madness and joke taken too far! Who took away Rochas Okorocha;s brain, please return it back oooo! Just listen to this Rochas mumu sister, you will see the craze has spread to family members! https://t.co/VqIEXc4fxK

Rochas Okorocha, a man who has spent more money on statues than he has on living human beings has now appointed his biological sister as “Commissioner for Happiness and Couples’ Fulfillment”. What sin did Imo people commit to deserve this embarrassment as their Governor?
