TAXI drivers in Southampton are to be quizzed by licensing chiefs over plans that could see cab numbers rise in the city.

It follows a move by government transport chiefs, who have demanded that local councils justify restricting the number of licences being issued.

The Office of Fair Trading has also recommended that licensing authorities should scrap the upper limit on hackney licences.

But cab drivers have warned that any plans to scrap the limits in Southampton would cause hardship to existing drivers and worsen the service for customers.

At a meeting of the city council's licensing committee on Thursday, members were told that the government had asked all local authorities to review the number of licences granted to cab drivers.

Councillors heard that a survey of unmet demand was needed by the council to strengthen any argument that licensing restrictions should remain in place.

Perry McMillan, from the Transport and General Workers' Union, argued that any plans to scrap the upper limit for taxi licences would mean that some drivers would not be able to use the city's taxi ranks during busy periods.

He said: "Imagine the impact that would have on people trying to earn a living.

"We are talking about people's livelihoods and families. You also have to consider the health and safety aspects if drivers are forced to work longer and longer hours."

Committee member Councillor June Bridle said: "I think it does this council credit that in the past it has constantly involved the trade.

"The points made are very valid if we are to continue to be a consultative council and continue to be concerned about how taxis are provided."
