David Cameron cautioned for giving early hint of GDP outcome Mr Dilnot said it was a "clear example of the difficulties and risks created by the current arrangements" for pre-release and repeated demands for a review of the system. "It is our view that the current pre-release access arrangements undermine public confidence in official statistics and the professional independence of statisticians," he warned. At Prime Minister's Questions, Mr Cameron reeled off a list of favourable recent economic indicators, before telling Labour leader Ed Miliband: "I can tell you, the good news will keep coming." Labour said the comment was a "clear reference" to the GDP figures for the last quarter, which showed an unexpectedly high 1% increase when they were eventually published this morning. Mr Cameron's official spokesman denied the claim. But Mr Dilnot - who has dubbed the pre-release arrangements "absurd" - said the controversy highlighted the need for reform of the system. Changes were promised by the Tories before the 2010 general election but have since been refused by ministers despite the watchdog's persistent campaigning. "We believe that the current practices for pre-release access to official statistics are unsatisfactory, not least because they put those who have received such access in a difficult position, especially when they have to speak in public after receiving access and before publication," he said in his letter. The interpretation of your remarks is a clear example of the difficulties and risks created by the current arrangements. Since responsibility for determining the pre-release rules continues to rest with government, we would urge you to undertake a review of these arrangements and I would be happy to meet your senior officials to help in taking this forward. A Number 10 spokeswoman said: "We will respond in due course. The Prime Minister was not referring to the GDP figures.
