[15] In his first months as prime minister, Brown benefited from a polling bounce, with Labour taking the lead back from the Conservatives.
[30] Designed by the agency, this poster involved an image of Brown looking modest, thoughtful, and wearing a lightly creased suit beside the advertising slogan[31] "Not flash, just Gordon".
[27][32] On 12 September 2007, because of the poster,[33][34] Labour and Saatchi signed a contract worth several million pounds, and the agency was given control over the party's advertising for the next general election.
[37] By 16 September, an advertising campaign for the slogan had been launched by the agency,[38] with the poster displayed on billboards and used in political adverts in preparation for a 2007 snap election.
[41] On 5 October, an opinion poll held by the News of the World had the Conservatives with a six-point lead over Labour in 83 swing seats.

[37][60][61] Philip Gould, who worked on the campaign, claimed that the slogan was a word play on the character in his 2011 book The Unfinished Revolution: How New Labour Changed British Politics Forever.
[27][36] The Campaign's Claire Beale said the original poster was "a great start" for any attempts by Saatchi to regain its 1980s prominence.
[66] The Independent's Andy McSmith echoed her opinion, saying that the poster gave Saatchi "the prospect of recapturing some of its former prominence".
The poster took advantage of the voters' positive views of Brown in his first months as prime minister, with his awkward traits making them believe that he was truthful and straightforward, and that he did not use spin.
Not you, just Gordon", in reference to Labour's refusal to call a referendum for the ratification of the Treaty of Lisbon, which affected the constitutional foundations of the European Union.
