Alex Salmond, leader of the pro-independence Scottish National Party, and Alistair Darling (not seen), 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 the debate on Tuesday can boost their campaign, which is lagging in opinion polls with only just over six weeks to go before a referendum.
