Ahmed Ali previously said that his daughter should not be allowed back in the country after travelling to Syria to join the terror group in 2015.
But today Ali said his comments were “misinterpreted” and pleaded for mercy from the English government.
Ali, who lives with his second wife in northern Bangladesh, told ITV: “My daughter was a little child, she made a mistake.
“She didn’t properly understand, I would like to make a plea to the British government not to strip her of her nationality.
“If she has made any mistakes, bring her back to London and let them do whatever they think is necessary.”
He added to AFP: “She may not have gone there [Syria] willingly. She may have been ill-advised by other people.”
Ali last saw his 19-year-old daughter in 2015, two months before she left her east London with two other schoolgirls, Cadiz Sultana and Amira Abase.
Begum is now languishing at a Syrian refugee camp with her newborn child after having her British citizenship revoked by the Home Office.
“Bring her back to London and let them do whatever they think is necessary”
Her sister, Renu Begum, has written to Javid telling him her family intends to challenge the decision and that her status is “a matter for our British courts”.
Renu said her remarks are “not representative of British values” and her family rejects them entirely.
“We wish to make clear, that along with the rest of the country, we are shocked and appalled at the vile comments she has made to the media in recent days”, she said.
However, the government is reportedly working on a new Treason Act to punish Brit ISIS members such as Shamima Begum.
Home Secretary Sajid Javid has supposedly ordered officials to close down legal loopholes so courts can properly prosecute traitors.
