In a statement given to ConservativeHome Tory MEP Roger Helmer has confirmed Guido’s many stories about the “mexican stand-off” he is in with Warsi and CCHQ:

I have made it clear that I will not sign the formal resignation papers until the position is clarified and Rupert is confirmed. I was happy to resign in favour of the next-in-line in the normal way, but I am not prepared to stand aside for some A-List Cameron protégée from St. John’s Wood. However the Party says it will not call the panel and make the decision until I do resign. So we have a Mexican stand-off.

I think that both I and Rupert (and our respective families) are entitled to some certainty and resolution on the issue. Accordingly I have indicated to the Party Chairman that if the situation is not resolved within a few weeks, I shall withdraw my offer to resign. 

I have also made it clear to the Party Chairman that I believe that my obligations on this point have been fully and finally discharged by my offer, made in good faith, to resign. Accordingly, if I am obliged to stay in place until 2014, I shall feel no further sense of obligation or responsibility to the Party.
