The Government has said it was the responsibility of the North East local enterprise partnership to notify an MP of an official visit to his constituency.
Sedgefield MP Phil Wilson accused Stockton South's James Wharton of visiting Mr Wilson's constituency without informing him first. The Stockton South MP said he was only 'dropping off' Local Government Minister Brandon Lewis, and denies taking part in an official visit.
A spokesperson for the Department for Communities and Local Government said:
“The visit was hosted by the North East local enterprise partnership who secured £289.3million from the Government’s Local Growth Fund to support economic growth in the area.
“As part of organising that event the local enterprise partnership agreed to make all local MPs aware of the minister’s visit.”

The rail firm Hitachi has moved its global headquarters from Tokyo to London, after winning a £1.2bn contract to build trains at its new factory in Newton Aycliffe in County Durham.
The Business Secretary, Vince Cable, said: "This move demonstrates a huge vote of confidence in Britain, its workers and its rail industry from one of Japan's biggest businesses. It follows the company's announcement last year of 750 new jobs at their factory in Newton Aycliffe."
The new purpose-built factory in Newton Aycliffe is expected to be operational from 2015 with full production starting in 2016.
A total of 270 carriages will be manufactured at the new plant, enhancing the factory's ability to win lucrative rail contracts across Europe.
