- Energy Secretary Ed Davey, Health minister Norman Lamb and Party President Tim Farron were among the keynote speakers
Former Lib Dem leader Lord Ashdown is asked about this afternoon'svote to reject attempts backed by the party hierarchy to change its stance on airport expansion. "We are a democratic party and the leadership doesn't always get its way," he tells BBC News.
With a show of hands party members vote to adopt the policy motion on the Middle East - and attention turns to a motion censuring the party's Federal Executive for "unconstitutional behaviour".
Nick Clegg, who makes his conference speech tomorrow, has said the Liberal Democrats would cut the taxes of 29 million working people in 2016 if they remain in government. The deputy prime ministertold the BBC's political editor Nick Robinson no-one would pay tax on the first £11,000 of income from April 2016, a £1,000 rise on current limits.
Menzies Campbell stresses that Turkey should be persuaded to "give up its stand off" and supply the Kurds with weapons to assist their fight against IS, warning that if the Syria-Turkey border town of Kobane - where fighting is raging - falls to IS, "there will be slaughter on an apocalyptic scale". He doubts that there can "ever be a more compelling case for humanitarian intervention".
Former Lib Dem leader Sir Menzies Campbell voices his support for UK involvement in air strikes against Islamic State militants in Syria. He says David Cameron should seek Parliament's approval to join US-led operations, to combat the "massive ethnic and religious cleansing".
This is the first of two "emergency motions" on topical matters being discussed by Lib Dem activists. The second is concerned with the party's Federal Executive.
Terry Wise in Chelmsford: After supporting Lib Dems most of my voting life, no more, they are no longer a viable ruling party, they have proved themselves to be a total non-entity, soon to be consigned to the parliamentary dustbin, a let down, disappointing to say the least.
Martin Horwood MP expresses the party's sadness at the death of British aid worker Alan Henning, who was killed by Islamic State (IS) militants. "He was one of the best of men, murdered by the worst," he says. The motion on the Middle East calls on the government to continue to work closely with international allies to stop the spread of IS "in Iraq, Syria and beyond".
Matthew Bambridge in London: This just shows that the Lib Dems have not grown as a party and are still unable to make sensible policy decisions. Britain needs an increase in runways to remain competitive in Europe.
The Liberal Democrats have moved on to the final item on the agenda, which begins with a discussion on the latest situation in the Middle East. Opening, Cheltenham MP Martin Horwood criticises what he says are "illegal" Israeli settlements in the West Bank and the country's "disproportionate" response to rocket attacks from Gaza. Mr Horwood explains that the motion before conference encourages a "united European stance that recognises Palestinian statehood".
Emma: My parents bought a house 32 years ago, 20 minutes away from Gatwick in a beautiful area. They spent 30-odd years doing it up. From the garden you could always see planes but noise was never a problem. Visiting this summer was terrible. You couldn't sit outside and chat as every few minutes you'd have to pause and wait for the plane to go by otherwise you couldn't hear yourself speak. If Gatwick is expanded my parents, like many others, will end up moving from the home they've lived in and worked hard to build.
It's a standing ovation for Lib Dem President Tim Farron, as he ends his speech with a call for the party to offer "wisdom amidst the hysteria". "This is our opportunity," he tells activists. "This is the Liberal moment. Let's grab it."
Tim Farron says more work is needed to achieve "real" equality, branding it a "moral outrage" that too often women are "paid less and matter less". He also notes that "our politics and our party" does not yet fully reflect society and says Lib Dems will redouble their efforts to change that.
Tim Farron says it is "ludicrous" that Britain's largest city - the capital - is more than seven times bigger than its second largest. London matters "far too much for its own good, and for the country's good," he adds.
Tim Farron criticises the notion of small government which he says creates weak citizens. He tells delegates he entered politics to make a difference, as he defends big government. He goes on to attack Conservative party policy commitment to scrap the Human Rights Act, saying human rights are not "frustrating" but integral to what it is to be British. They are the legacy of Winston Churchill, Mr Farron adds, and remarks that the former PM would once be a liberal once again today. He says David Cameron is "no statesman".
Britain's future is as an open, inclusive society, Tim Farron tells Lib Dem conference, warning that the "nationalism" and "isolation" of Conservatives and UKIP is a "serious" threat.
Tim Farron defends immigration, telling activists migrants make a "net contribution" to the economy and should be celebrate not "demonised". He adds, to applause: "We should be grateful that migrants have chosen to relocate their lives here and are working to build our economy."
Tim Farron says other parties are "panicked by the rise of the populists, with a beer or a whisky in one hand and a simplistic solution in the other".
Tim Farron says politics today "disappoints" for so many people because globalisation has made them "feel powerless, insecure and uncertain".
Party President Tim Farron gets a round of applause as he takes the stage to deliver a speech to party activists. It will be his final conference speech in this capacity, as he is standing down as president.
The debate culminates in several votes. The Ageing Society policy paper is adopted by the conference - without amendment.
Former Care Minister Paul Burstow is wrapping up the current debate in the main hall, on Britain's ageing society. He urges members to reject the "siren calls" of those who want to "pitch generation against generation" - and appeals to conference to keep the triple lock pension guarantee in the policy paper. "Let's not start not stepping back from our commitments to pensioners," he says.
Two Lib Dem ministers - Scottish Secretary Alistair Carmichael and Pensions Minister Steve Webb - are watching this afternoon's debate about Britain's ageing society.
Outside the conference hall in Glasgow, the mists have cleared to leave a glorious sunny afternoon (see earlier picture at 09:42)
Malcolm Lenaghan: The global population is growing, trade is growing, transport demands are growing both on land, sea and air. The UK needs the extra runway capacity in the South East because the mass of population lives there. Alternatively should we all get in our cars and drive to Birmingham, Manchester or Glasgow airport thereby causing further increase in greenhouse gases?
Barbara Smith describes herself as "a baby boomer, still dancing to the Rolling Stones", as she contributes to the ageing society debate. "We are the grey pound and the marketing men love us," she tells the hall. But she makes the case for a reassessment of universal pensioner benefits to provide more support for struggling younger generations.
Nick Clegg is not facing any leadership challenges at this year's Liberal Democrat conference - but will he still be in charge time next year? And how many MPs will the party have?Read what Lib Dem members say
Coming up at 16.10 BST, Lib Dem President Tim Farron will address activists. This'll be followed by debates on so-called emergency motions on topical matters, including the situation in the Middle East, and the Federal Executive's "unconstitutional behaviour and gender quotas for committee elections".
This councillor is applauded as he ends his contribution to the pensions debate with the words: "Nigel Martin, signing off, a pensioner still in his prime."
