A new mum passed her driving test, only to be told she had actually failed one day later.

Kelsie Murphy received the phone call from the Herne Bay test centre notifying her of the admin cock-up on her birthday.

She thought she had passed with six minors - but a major error was recorded on the test certificate either after the test or during it and the examiner had forgotten to note it down.

It is thought the 22-year-old is the first person in Britain to have had her licence revoked before even receiving it.

Ms Murphy said: “I have no idea where the major mark came from.

“As far as I knew, everything had gone smoothly.

“I feel like the unluckiest person ever because they told me it hasn’t happened to anyone but me.”

The mum-of-two took the test on April 11 at the centre in Altira Business Park.

Drivers must have less than 15 minor faults and no majors to pass.

She said: “My examiner said ‘congratulations, you’ve got yourself an early birthday present - you’ve passed’.

“I was so happy, nearly crying, but holding myself back because I didn’t want to embarrass myself.

"The examiner is still sure that I should have passed, so we have no idea what’s happened" - Kelsie Murphy

“My driving instructor came running over to me because she could see the smile on my face.

“The examiner went through the paper with us, showing me that I only had six minors.”

Ms Murphy, from Broadstairs, was ecstatic to have passed after failing on her first attempt.

Her mum had helped her buy a car and she sent her papers off to the Driver and Vehicle Licensing Agency, in order to get her driving licence.

A day later, while she was celebrating her birthday, Ms Murphy received a phone call from the test centre demanding she return the pass certificate.

It then told her she had not passed.

A letter addressed to her on April 14 from Mark Aston of the Driver and Vehicle Standards Agency (DVSA) said: “After your test on Wednesday 11th April at 13:35 our in-house checks identified a serious fault had been assessed and recorded during your test but due to an administrative error, your examiner issued a pass.

“With this in mind, I am sorry to confirm that you have not passed your driving test and that you should only be driving in accordance with the provisional licence regulations.

“Finally, please accept my sincere apologies for any upset and inconvenience that this error may have caused.”

Ms Murphy said: “I just didn’t get it. The man passed me and he wouldn’t have done so had the serious mark been there.

“The examiner is still sure that I should have passed, so we have no idea what’s happened.”

The test centre, which is run by the DVSA, has offered Ms Murphy a free retest but she declined as she believes she has already passed.

Now, she is without a licence while an investigation takes place.

She said: “It’s really upsetting and stressful to have to go through this and it makes me want to give up on my driving.”

DVSA operations director, Richard Hennessey, said: “DVSA is unable to comment on any ongoing investigations, but we apologise for any inconvenience this error may have caused.”
