Sir – I fully agree with the comments of Roger Moreton (Letters, July 21) concerning the congestion caused by students visiting the city. From casual observation, the influx this year seems to exceed previous years by some way and to be in Oxpens Road in the morning is like watching the movement of the nations with coach after coach after coach unloading their passengers.

It has to be asked if the majority of students are really interested in the sights of the city. I suspect Primark is of more interest to them. I recently opened a historic building to a party of 100 visiting teenagers and they showed not the slightest interest in the building or its history.

They are of only marginal economic value as they tend to bring their food and drink with them and such numbers discourage other shoppers from venturing into the city centre where it has become necessary to often push students out of the way.

Last week, I saw a woman fall over a group of students who had sat down in the middle of Cornmarket. The police cannot be counted on to control the crowds, as Mr Moreton suggests, as they are highly selective in the laws which they choose to enforce.It would be no great problem for the city council to devise a capacity limit for the city and inform the language schools across the South of England that no parking space will be available for student coaches unless booked in advance.In this way it would be possible to exercise a degree of control and make the experience of visiting the city an enjoyable one, rather than hectic scrum.
