Gordon Brown wants expenses put on the internet and web inventor Tim Berners-Lee to improve access to government data, he said in a speech today.
The Prime Minister was addressing the issue of constitutional reform following the expenses scandal which has rocked the government.
He said in a speech in the House of Commons, "So that government information is accessible and useful for the widest possible group of people, I have asked Sir Tim Berners-Lee, who led the creation of the worldwide web, to help us drive the opening up of access to government data on the web over the coming months."
He added, "All MPs' past and future expenses should and will be published on the internet."
He predicted that the move would improve transparency, and "given the vital role transparency has played in sweeping away the decrepit system of allowances, and holding power to account, I believe we should do more to spread the culture and practice of freedom of information".
Brown's comments came a few days after the Cabinet Office published a blog saying it was looking at ways of improving access to government data, following the example of the Obama administration, which has launched data.gov.
