Mrs Allison-Madueke is said to be in a critical condition from an undisclosed ailment in a London hospital.
“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 family said.
On those calling for the probe of the former minister, the source appealed for balanced coverage of some of the opinions being bandied around by different interest groups.
“The press, especially online media, should be careful to be professional and balanced in their reporting,” a family source added.
