Thank goodness we now have two major differences (one of emphasis) on matters of policy.
Duncan Borrowman points out that Chris Huhne (note please that I don't call him "Chris") has started putting real emphasis on the green agenda.
But the big difference which has emerged is on the totemic issue of Trident, as the Observer reports:
Liberal Democrat leadership contender Chris Huhne last night moved to seize the initiative from his front-running rival Nick Clegg by breaking with party policy on keeping Britain's Trident nuclear missiles.
Huhne told The Observer it would be 'ridiculous' to spend up to £15bn updating the ageing submarine-based nuclear arsenal, describing it as a Cold War relic. He also argued this would risk further tying Britain to American policies, something he suggested should be avoided in the wake of the Iraq war.
