Cameron is not interested in having a head to head with Miliband because he knows he will lose the debate on the NHS and be made to look like a liar in front of millions, he will also be pulled apart on his disastrous policy failure on Immigration.

He will probably opt to call a short debate with strict time limits on each question or topic and with at least seven other Political Party's taking part he knows Labour will not have enough time to put him on the spot. He will effectively hide in the shadows and throw out sound bites knowing that time constraints will save him from closer scrutiny.

This has been his plan all along imho.
