David Cameron was left red faced, at prime minister's question time, by Sunderland Central MP Julie Elliott.
Ms Elliott asked why the olympic torch was not coming to Sunderland.To hoots of derision from the opposition, an embarrassed Mr Cameron admitted that he could not answer the question because he did not know where Sunderland was.
A surprised Ms Elliott explained that Sunderland stood at the mouth of the River Wear, in the north east of England.It was also the biggest city between Leeds and Edinburgh.
Mr Cameron admitted he was no wiser.
"That does not surprise me in the least," said Ms Elliott, "Because for the past thirty years, the conservative party has tried it's best to wipe Sunderland off the face of the map. We've lost our shipyards, coal mines, port, glass works, brewery, engine works, clothing industry and just about every thing else apart from our pride. All we have left is the most productive car plant in Europe."
A look of recognition came to Mr Cameron's face. "Now I know where you mean, Nissan. Isn't that in Newcastle?"
"Newcastle? F+++ing Newcastle? No it's not, it's in Sunderland, home of the friendliest people in the country.The place I am proud to call home." sobbed an emotional Ms Elliott.
"Oh, er, I'll see what I can do about the torch."
