The BBC's political editor went back over the exchanges at PMQs after David Cameron pledged an in/out referendum in the early part of the next parliament if his party won the 2015 general election.
Nick Robinson reckoned Tories believed they had Labour in a trap, while both sides claimed their opponents were not answering questions.
He debated the questions and answers with Andrew Neil, Labour's Caroline Flint and Conservative Party chairman Grant Shapps.
