Nick Clegg says much progress has been around mental health, but that more work is needed. He wants a society where people feel as comfortable discussing their mental conditions like stress or anxiety, as those with a sprained ankle.

Here comes the section on mental health, trailed before the speech. Nick Clegg says he wants to end the "Cinderella" treatment of mental health services.

Another commitment from Nick Clegg, this time to raise the personal income tax threshold to £12,500 by 2020. Labour would never have made this change because it liberates people from the state, he says, and claims the Conservatives were always resistant to the proposal, branding it "your tax cut, Nick".

Nick Clegg says the Lib Dems are committed to expanding childcare to all two to four year olds, and for healthy lunches for all primary school children. "Education, opportunity. That is what the Liberal Democrats are all about," he tells the hall.

Turning to education, Nick Clegg takes aim at former Education Secretary Michael Gove who he accuses of raiding the schools budget to pay for his free schools "obsession". He says the biggest coalition faultline has been "the way in which self-proclaimed Conservative educational reformers sought to suffocate almost every single initiative designed to instil opportunity at an early age - for all children, not just some".

Getting vested interests to give up their hold on powers is one of the hardest things about being in power, says Nick Clegg. He criticises Labour and the Conservatives for blocking reforms to the House of Lords, and party funding. He also accuses the Tories of pursuing English votes for English laws for party interests.

The Lib Dems care passionately about civil liberties Nick Clegg says - and urges Home Secretary Theresa May to stop "playing party politics with national security" and "playing to people's fears". He says her Communications Data Bill was "disproportionate" and makes clear that the Lib Dems have blocked it before and will do so again.

Citing the London riots, he says that if you give people a future "they won't trash the present". But Britain is still a place where opportunity is handed down like an heirloom, not spread around like a universal right, Mr Clegg laments. Only the Liberal Democrats can create a fairer society that creates opportunity for everyone, he insists.

The Liberal Democrats stand for a different type of politics, Nick Clegg declares, and not the politics of "us and them" and "blame and fear". We must give people what they "lack yet crave", the party leader tells activists. Government can't do everything for everyone but it can try to level the playing field so people have the chance to get on, Mr Clegg adds. "Opportunity for everyone," he emphasises.

Turning his fire onto his coalition partners, Mr Clegg claims the Conservative leadership believes every worry can be fixed "with a big wave" of the Union Jack flag. He says the Tory pledge to reduce net migration has been "quietly ditched", and accuses them of "dragging their feet" in introducing border controls. He criticises Tory manifesto commitments, such as the welfare freeze, and claims they will have to be paid for by deeper public spending cuts.

In an attack on the Labour Party, Nick Clegg claims Ed Miliband is "promising a new Nirvana" where everyone will be well-off and no spending cuts will be needed. The party has no new plans to offer, or anything to say on how to fix the deficit, he claims.
