Information watchdog says Cabinet Office must provide details within 35 days

David Cameron will be obliged to disclose more details about the refurbishment of his Downing Street flat, following a ruling by the information commissioner.

The information watchdog ordered that the cost and specifics of work carried out on the flat’s bathroom must be made public, as well as any instructions the PM or his wife Samantha gave to the architects, builders or anyone else working on the project.

Christopher Graham, the information commissioner, chastised the Cabinet Office for delaying answers to questions submitted by Labour MP Tom Watson under the Freedom of Information Act.

Watson has demanded that Cameron “come clean” about his bathroom “makeover”, saying taxpayers have the right to know how their money has been spent.

The Cabinet Office must now provide the information within 35 days.
