Immediate past minister is said to be in a life-threatening condition from an unnamed disease in a London hospital.
The family said: “Our daughter has been in hospital where is receiving treatment for some weeks now. She is currently under close medical observation. We learnt that the observation means that she has been unable to see anyone outside close family members over the last few weeks.
“They have also discouraged her use of phones to avoid any risk of infection which will be extremely harmful for her.
“Diezani is responding well, but doctors are concerned about her movement and interaction given the intense treatment being administered.
“It is such an emotional time for us all as she is quite fragile and we are careful to keep her away from all the gossip and falsehoods being attributed to her in the media. We expect the media to respect the family’s feelings at this trying time.”
The source especially asked those calling to investigate Diezani for balanced coverage of some of the opinions being discussed around by various interest groups.
He added: “The press, especially online media, should be careful to be professional and balanced in their reporting.”
There had been reports that former minister is suffering from cancer.
It should be mentioned that Nigerians are waiting to see Alison's Madueke's account for the 20 billion dollars the former CBN governor and now Emir of Kano, Sanusi Lamido Sanusi alleged was sidetracked from the Nigeria’s account by the minister and her associates in NNPC.
Apart from this, Diezani Alison-Madueke was also accused of squandering millions of dollars of public funds to rent private jets for the conduct of her official activities.
