A supermarket giant has dismissed claims it made state school pupils queue outside an Edinburgh store while admitting children from a private school.

It follows an allegation children from Boroughmuir High were discriminated against at the nearby Tesco Metro store in Bruntsfield.

A parent alleged pupils from the council-run secondary had to queue outside the shop while their counterparts from George Watson's College were able to bypass the line.

The row broke out after the father sent a tweet to Tesco to highlight the issue.

Tesco hit back at the claims, saying they were "completely untrue".

The supermarket chain said it enforced a queuing system for all pupils over the busy lunchtime period, when more than 100 children can converge on the shop at one time.

A Tesco spokesman said: "This is completely untrue - there has never been any discrimination between state and private school children at this store."
