Gordon's secret meeting in Europe

What was Gordon Brown's secret meeting with Labour MEPs about? That the question that Hugo Rifkind is asking. It appears he got sent round in circles trying to find out,

“It wasn’t secret,” says the Treasury press office. “Although we can’t tell you what it was about. You should speak to the Labour Party press office.”

“We don’t know anything about it,” says the Labour Party press office. “Try Gordon’s special media adviser.”

“What was it about?” says Gordon’s media adviser’s PA. “I couldn’t say. Maybe you should try the Treasury press office.”

Any takers got a theory?
