More than 60 letters due to be delivered by post company TNT have been found dumped in a residential street.

The post was found last night in Charlton Road, Kenton, and included letters from banks, hospitals and schools, all with TNT stamps on.

In February this year TNT announced it was expanding its postal operation into north west London with new delivery operations in Harrow and Brent.

Nirmal Valjii 42, who found the letters, said: “It’s very worrying to be honest. You expect your mail to be delivered properly and not just dumped in the street for anyone to find.

“Now I’m worried about my mail being delivered to me or it whether it’s being left in the street.

“It is very frustrating. You expect a level of service and professionalism because these are important letters which have just been left for anyone to find.”

This is not the first time mail has been found dumped by TNT, with some people forced to deliver letters to their neighbours.

MP for Harrow East Bob Blackman voiced concerns about the reports.

He said: “It’s certainly alarming that vital business post, including sensitive financial documents, failed to be delivered. Even more so that this is not the first incident that has been reported.

“Anecdotally, I was informed of someone being asked for directions by a lost TNT delivery man, which is concerning because I visited the TNT delivery office last week and was assured that their postmen were given informed of the local area routes as a matter of course before being sent out."

Mr Blackman said the deliveryman may have had difficulty finding the correct address but said that was “no excuse" to provide such a "lackadaisical" service.

The MP added: “I will be taking the matter up with TNT’s management in order to encourage appropriate action to be taken now, before any similar incidents can take place.”

A TNT spokeswoman said: “The mail has been collected from the police and we are now investigating this case and will work to resolve it as quickly as possible.

“We would like to apologise for any inconvenience caused. On the very rare occasions when an operative has deliberately failed to deliver mail we will take the necessary disciplinary and legal action.

“Their isolated actions do not reflect the dedication and hard work of the vast majority of our employees.”

Earlier this year Royal Mail raised concerns about over the expansion of TNT into north west London.

Anton Harding, delivery director from Royal Mail, said: “Royal Mail operates to one of the highest regulatory requirements of any postal services provider throughout the EU.

“Royal Mail’s competitors are not required to meet regulated standards for delivery.

“A level playing field in direct delivery competition would benefit consumers and secure the long term sustainability of the universal service. There is a need for transparency around service quality and mail integrity.”
