A Glasgow private hire driver is under investigation for allegedly refusing to allow Irish visitors to speak their language in his car.

The man, who has not been named, has been accused of offloading the passengers at the side of the road at 2am on a Monday morning after they objected to his demand that they stop speaking in Irish Gaelic. Enforcement officers from Glasgow City Council are now looking in to a formal complaint against the driver, who works for Hampden Cabs.

A city spokesman said: "A complaint regarding an alleged racist incident has been received and will be investigated in the appropriate manner by the council's taxi enforcement team."

Kathleen McAleer, 21, a mental health nurse, was one of four passengers in the car in the early hours of Monday, December 16. She was travelling with a friend and two first cousins from County Donegal from one house on the South Side to another.

The cousins, Joseph and Anthony Blair, 19 and 21, respectively are native speakers of Irish Gaelic.

Ms McAleer said: "My cousins were just talking to each other in Irish, which is their first language.

"The taxi driver turned around and said to them 'Stop speaking in that language'.

"We didn't really know how to take it. He said: 'When you are in Britain, it is English you speak.'

"I said to the driver 'Excuse me', shocked that somebody would say that to them."

I said: 'That is out of order'.

"He then said: 'If they want to speak in that language they can get out of my taxi.'

So we got out and said we wouldn't pay."

Ms McAleer reported the matter to both Hampden Cabs and the city council.

The Evening Times asked Hampden Cabs to comment on the complaint.

Initially the company's Paul Muir insisted the incident related to what he called drunken passengers who had been at a city concert the previous day who had allegedly intimidated an elderly driver and been asked to leave the car.

However, after being told Ms McAleer was reporting an incident a day before the concert, he said he would not comment.

But before doing so he said: "I couldn't imagine four people coming over from Donegal and going to a party in Britain and not being drunk"."

He then laughed.

Private hire and taxi drivers must prove they are a "fit and proper person" to hold a licence from the city's licensing committee.

Investigations are carried out by the city council's enforcement team with any findings passed on to the committee for a hearing, should one be deemed necessary.
