Euro RSCG Wnek Gosper, which helped steer Ken Livingstone to victory in the London mayoral elections, has already submitted designs for a new “corporate identity” for the capital.
The logo designs are believed to have been favourably received by the fledgling Livingstone administration.
But the Mayor’s communications adviser Harry Barlow has insisted that Euro would not be given favourable treatment – and that there would be a competitive pitch before a new design was chosen.
He said Euro RSCG had designed backdrops for the official launch of the Greater London Assembly at the Tate Modern next week.
His comments come amid accusations of cronyism in Livingstone’s administration.
GLA chairman Trevor Phillips is this week expected to ask for a full list of Livingstone appointments and how much they are being paid.
Euro account director Nick McElwee said the agency had continued to generate ideas for Livingstone since his election victory.
“We are still being carried along by the momentum of the campaign. I don’t want to sit back and wait for others to come up with ideas,” he says.
The GLA is expected to spend up to &£10m a year on advertising.
Many in the ad industry believe Euro RSCG’s close relationship with Livingstone makes it favourite to land a place on the GLA roster.
Euro RSCG chief executive Brett Gosper says the agency had produced some designs for Livingstone but had not received any official feedback.
He adds: “Anyone could have written in with ideas.”
