Iraq votes on Sunday. It is a critical stage in the country's development and turnout is expected to be high. But with 511 candidates barred from standing because of former links with the Baathist party, will sectarian rivalries compromise the credibility of this key election? Sir David speaks to Saleh al-Mutlaq, the head of the Iraqi National Front and one of the most prominent politicians excluded from the ballot paper. Plus, on Saturday Icelanders will vote on a referendum to decide whether the country should repay $5.1bn to the British and Dutch governments. The governments paid that sum to bail out savers who lost money when an Icelandic bank collapsed in 2008 - and now they want Iceland to pay it back. But will Icelanders cough up? Sir David talks to Icelandic journalist Sigrun Davidsdottir.
