A great scoop overnight for ConHome's Jonathan Isaby suggests that all might not be plain sailing for the Tories in the Euro Election on June 4th - the final major test at the ballots before the general election.

For Lynton Crosby, the Oz campaign Guru who managed Boris successful bid for the London Mayoralty last year, has now been engaged by Libertas - the Irish-funded political party that is planning to field candidates in every part of the EU in June's elections - including in the UK where they'll be competing with the Tories. It was Libertas, it will be recalled, that came to the fore in the successful move to stop Ireland signing up to the Lisbon treaty.

    The very idea that the man who engineered the Tory victory in London last year could now be working against the party will give a real boost to Labour campaigners up and down the country this morning and will go down like a lead balloon within the Cameron Quartet

For it is possible that the Euro Elections - already a potential disaster area for Labour - could also impede Cameron's Conservatives as they seek to build momentum for the big one - the general election.
