You asked

I would like to request the following information:

What is the total budget for the advertising campaign for the UK government to support REMAIN using Google Adwords over the life of the campaign.

I am looking for total allocated budget as I appreciate the campaign will not yet be spent.

I would also like actual budget spent on Google Advertising by the UK Government on Google Adwords supporting REMAIN over the life of the campaign once the referendum ends.

Thank you for your request. We can confirm that the requested information is not held by the Office for National Statistics. We are unsure of who would hold this information however, it may be worth contacting the Electoral Commission or HM Treasury to see what information they are able to supply.
