Lack of GNER services raised by Paddy Tipping

In a recent parliamentary debate on Network Rail, Paddy Tipping MP asked the Transport Minister Derek Twigg to investigate:

Does greater co-operation include discussions with the Office of the Rail Regulator? Will my hon. Friend look particularly at services on the Great North Eastern Railway main line, where the Office of the Rail Regulator has blocked plans from GNER to deliver the extra 12 services promised in its franchise?

More information on this issue can be found in this article. Since this debate, the Regulator is reconsidering their decision to favour services by Grand Central at GNER's expense as reported in Rail News, which notes there have been "reports of strong pressure from the government and GNER", part of which has evidently been applied by Paddy Tipping.
