Sir Menzies Campbell: Gaddafi will not go without a fight
Sir Menzies Campbell, former Liberal Democrat leader, urges caution and warns that Gaddafi will not go without a fight:
"There's a lot of support for Gaddafi in Tripoli and a lot of it is armed, manning road blocks.
"My sense is he won't go without a fight. He won't go without pulling the temples down around him."
"I don't think this is the rebels advancing to gate of Tripoli.
"I think this is the dissidents in Tripoli who, having seen recent events, have been emboldened about making a practical demonstration."
