The ads were commissioned by the Tories before the General Election earlier this year, but are understood to have been shelved over concerns that their provocative content could cause a backlash at a time when the party felt secure of its position in the polls.
Running under the "I've never voted Tory" strategy, the striking ads take a refreshing change of approach to the usual political fare, addressing subjects traditionally considered too edgy for UK voters.
But when ±±¾©Èü³µpk10 contacted Euro RSCG, the agency behind the ads, to confirm that it had created them, legal action was threatened should the ads, or a description of their content, be made public.
Euro created most of the Tories' pre-election advertising, but in March, M&C Saatchi was drafted in to work alongside it on communications.
Since coming to power, prime minister David Cameron insisted that the new government should take a more open approach.
At the end of May, he pledged "greater transparency" and promised to remove the "cloak of secrecy" from government affairs.
