In the case of Somerset he said:
'We have asked the commission how the costs and savings of the three unitary option recommended in their report might vary under alternative three unitary options that did not involve splitting Mendip.'
In the case of North Yorkshire and North Humberside, the commission's report gave estimates of costs and savings for a range of options for the whole review area north of the Humber.
'The estimates of potential costs and savings are important considerations that will inform our decisions,' Mr Baldry said.
'In both these cases we feel that further information on how costs and savings might vary between alternative options will help all concerned to assess which option is likely to be most cost effective.'
