Why so coy OFS?

I read in The Telegraph today that the Office for National Statistics (OFS) "is not publishing its annual survey of the country's most popular names for babies because of cost-cutting - really, is that so, or is there a more prosaic reason?

Last year I reported that taking into account the various spellings Mohammed was now the second most popular name for a boy in the UK - the various spellings being Muhammad, Mohammad, Muhammed, Mohamed, Mohamad, Muhamed and Mohammod as well as Mohammed.

Could it be that including variants Mohammed was the most popular name given to a baby boy in 2008?
