A Home Office spokeswoman would not confirm if the deportation of Afusat Saliu and her daughters to Nigeria has been delayed, saying it does not comment on individual cases.
Ms Saliu told ITV News she fears her two daughters, four-year-old Bassy and two-year-old Rashidat, will be subjected to female genital mutilation in her native Nigeria if they are deported.
Last night, Virgin boss Sir Richard Branson was flooded with more than a thousand tweets urging him personally to step in to block the flight.
He later tweeted:
Call upon UK & Nigeria governments to do all they can to protect Saliu family & ensure they aren't put at risk of FGM http://t.co/qyGIIqWPLQ
