The publication of key retail sales figures used to evaluate the UK's economy has been delayed due to concerns about the "quality" of the data.
The Office for National Statistics (ONS) has pushed back the publication of its monthly retail sales figures by a fortnight for "further quality assurance".
ONS data is utilised at the top levels in forming government policy and setting the Bank of England interest rates.
The BBC reports it has apologised for any "inconvenience caused".
It marks the latest setback for ONS following confusion and disruption about the accuracy of the UK's inflation rate for April.
The organisation said the rate was too high as a result of it being incorrect road tax data from the Department for Transport.
And in June, a government review found "deep seated" issues at the ONS which it said would need to be addressed to "rebuild its reputation".
