When I first realised that the manifesto launch was going to take place in a nightclub, I was slightly concerned, given last year’s lacklustre launch in the Ministry of Sound. Lessons have very clearly been learned from that launch. The backdrop was brightly coloured, the place was full of people. Even watching on the television, the atmosphere was clearly buzzing. One reporter even referred to it as “the love lounge.”

Until the technology failed him and cut the event short, Nick Clegg was on top form. If this party ever needed a leader at the top of his game, it’s now and he delivered. He set out in convincing form why he and not Nigel Farage or the SNP needs to be in the next government. His was a message of optimism underpinned with responsibility. For me, the “enabling everyone to get on in life”, which later morphed into Opportunity for Everyone, is the most important part of our message, and it was elevated to centre stage today:

At its heart is one word that is absolutely central to what Liberal Democrats believe: opportunity. No matter who you are, where you were born, what sexuality or religion you are or what colour your skin is, you should have the same opportunity to get on in life. We want to tear down the barriers that stop you from reaching your potential. We want to smash the glass ceilings that keep you from achieving what you want to achieve. Your talent and your hard work, not the circumstances of your birth, should decide what you can be.

When we formed the Coalition in 2010, three quarters of our manifesto became part of the Government’s agenda. The priorities on its front page: fairer taxes; investment in the poorest children in schools; fixing the economy; and political reform, became central to what the Coalition Government did.

That’s why this manifesto matters. It is a programme for a liberal Government with decency, tolerance and generosity at its heart.

That for me is the best bit of his speech. The heart and brain stuff is what everyone is talking about, with as many Wizard of Oz comparisons as you like, but remember that that leaves us as the little lion who finds out that it actually does have loads of courage.

While Cameron has been telling Middle England that the only way to protect themselves from the nasty SNP doing ever-more ridiculously implausible deals with Labour is to vote for his party, Clegg has come back today and told those same voters: It’s ok, I’m here, I’ve done it before, you know I’m sensible. He’s presented his record, showing how he kept his word and delivered his priorities from last time and outlining how he intends to build on that over the next five years. Values, consistency and clarity may yet prove compelling for the electorate.
