Alex Salmond, leader of the pro-independence Scottish National Party, and Alistair Darling (unseen), head of the "Better Together" anti-independence campaign, take part in a television debate in Glasgow August 5, 2014. Supporters of Scottish independence are hoping leader Salmond's performance in a U.S.-style television debate on Tuesday can boost their campaign, which is lagging in opinion polls with only just over six weeks to go before a referendum.
