A promising teenage student based in north London has been told she will be deported to her native Mauritius without her family - on Mother's Day.

Yashika Bageerathi, 19, has been given plane tickets by the Home Office and told to leave the UK alone on Sunday or "removal may be enforced", according to a spokesman for Oasis Hadley Academy in Enfield.

The tickets are for Air Mauritius airline and the spokesman added that students' unions across the capital were expected to go to their London office to call for the airline to refuse Ms Bageerathi on to the flight.

The spokesman added the tickets were only for the teenager, meaning she will be forced to leave her mother and siblings alone on Mothers' Day.

Air Mauritius said it would not comment on individual passengers and the Home Office has repeatedly refused to discuss the case.

The teenager came to the UK with her mother, sister and brother in 2011 to escape a relative who was physically abusive and claimed asylum in the summer of 2013, although all four now face deportation.

Ms Bageerathi is still in Yarl's Wood Immigration Removal Centre where she has been since Wednesday, March 19, and it was hoped she would be released on bail from the centre this week, a campaign backed by her MP, David Burrowes who represents Enfield Southgate.

On Thursday, Home Secretary Theresa May told Sky News it would not be appropriate to "interfere" with the case.

Ms May told Sky News: "Yashika's two claims to appeal against the decision on her asylum claims have been dealt with by the judges, they've been looked at by the judges and I don't think it's appropriate for a politician to interfere in that legal process."

She said the plight of the teenager had gone through the "proper process" and she would not be stepping in to prevent her deportation.

It seemed she had been given a last minute reprieve on Tuesday, when British Airways appeared to refuse to allow her to board a flight from Gatwick Airport, but the airline would not comment on this.

The campaign was dealt a blow when her mother, brother and sister were told they also faced the threat of deportation after receiving a letter from the Home Office telling the mother she had no grounds for appeal.

A petition by the students calling on Immigration Minister James Brokenshire and Theresa May to stop the deportation and allow the student to complete her A-levels garnered more than 140,000 signatures on change.org.

Oasis Hadley headteacher Lynne Dawes said she was on her way to the Mauritian High Commission with a small group of students to ask Air Mauritius not to allow Ms Bageerathi to leave on the flight due to take off from Heathrow at 5pm.

She said: "We're absolutely horrified because it's only Yashika. Our argument is still the same: not to send her back by herself. We're just really concerned and we're trying to do what we can to help.

"We're really worried about Yashika. She's really upset, as is her whole family."

Mr Burrowes said on Twitter that he had not heard back from the Home Office despite making official representations to Mr Brokenshire on Monday and Wednesday, and condemned the letter from the department as "out of order and wrong".

The Conservative politician has previously said the student cannot leave until the minister responds to him.
