The Conservatives are pushing their green credentials, but are not using their party's national slogan, 'vote blue, go green', Today reported.
Conservative councillor John Hawkswood told the programme: 'If you're coming down heavily on flyposting, it's somewhat hypocritical to suggest we put up billboards and election posters at the same time.'
The Conservatives' hold on Solihull is being challenged by the Liberal Democrats, who gained a parliamentary seat in Solihull last year.
The Conservatives also have internal divisions, Today reported. Rosemary Worsley, former Conservative chief whip on the council, is standing as an independent in next week's elections. As well as opposing the council's cuts in music education, she told Today she disagrees with David Cameron's policies. 'This isn't the party I joined the party of low taxation', she said.
