A report suggesting a new Tesco supermarket in Hadleigh could lead to serious traffic problems has been dismissed by county highways chiefs.

Hadleigh Chamber of Commerce commissioned the report, which stated there was a “one in 100 chance” of an accident occuring if the retail giant gets permission to build on the former Brett Works site. The report also said Tesco’s own traffic flow study relating to the planning application was “seriously flawed”.

But the county council has commissioned its own review, which refutes the protestors’ claims.

A spokeswoman for the authority said: “We have very carefully considered the points put forward by the Hadleigh Chamber of Commerce consultants, but remain of the view that there are no highway grounds to recommend refusal of the application as long as suitable conditions and obligations are met.”

Tesco corporate affairs manager Simon Petar added: “We are pleased that Suffolk County Council, having reviewed the chamber’s submission, is satisfied with our detailed independent and expert analysis.”

However chamber member Roger Bannister said despite submitting a lengthy report pointing out the deficiencies and dangers in Tesco’s application, they had received no response from the council other than a “brief dismissive email”.

He added: “What is even more concerning however is that Tesco has been made aware of a spreadsheet detailing the county council’s responses to our concerns, yet neither the chamber nor the public have been made aware of this document, which is extremely concerning.” The application is likely to be decided in August.
