Reformists Group (ECR Group), which is affiliated to the ACRE. Party leader David Cameron pushed the foundation of the ECR, which was launched in 2009, along with the Czech Civic Democratic Party and the Polish Law and Justice, before which the Conservative Party's MEPs sat in the European Democrats, which had become a subgroup of the European People's Party in the 1990s.

The results were that recognition of the symbol was low and that people found it old fashioned and uninspiring. It was decided to redesign the existing logo, rather than adopt an entirely new one which might be interpreted as signalling a change of the party's ethos. Using a design company headed by Michael Peters, an image of a hand carrying a torch was developed, which referenced the Statue of Liberty. In 2006, there was a rebranding
