Pensions Minister Steve Webb is addressing party activists on pensions reform. He says former Conservative PM Margaret Thatcher broke the earnings link with pensions which reduced the real value of the pension over time. Mr Webb says it will take time to reverse this but that progress is being made thanks to the triple lock guarantee introduced by the coalition.

Jamie Rose in Hounslow: This seems to be a really short-sighted policy. I understand there is a balance between environmental impact of aviation against the benefits of major UK hub airports brings to our economy. If a party is struggling with its conscience, such as the Lib-Dems, the Gatwick option is a reasonable compromise.

Alan in Durham: No expansion of airports in London or indeed south of Birmingham should be considered. Infrastructure to Northern airports should be improved and these airports should be used or expanded. Another example of everything within the M25 club.

Pat Mooney in Cheltenham: This decision will come back to haunt the Lib Dems both in their opposition to an additional runway at either Heathrow or Gatwick and no expansion at all in any part of UK. It shows how distant they are from business, UK travellers and the wider international community.

Party members are now discussing a policy paper on an ageing society. It recognises the challenges posed by people living longer and states that "Liberal Democrats take an optimistic view of ageing and the opportunities it presents".

Ed Davey stands by the party's record in government and says he is proud of what it has achieved. "So let's get out there and tell people, tell them how we much we've changed the old way of doing things, how much we are going to keep on changing things," he says, to applause.

BBC News website reader in Crawley: Crawley is only a few miles from Gatwick and would benefit greatly from a second runway. It's annoying living so close to Gatwick and often having to travel to Heathrow.

On the attack again, Ed Davey says some Conservatives colleagues "don't share our passion for a fairer society". He goes on to say the Liberal Democrats have led the climate debate in Britain and that his mission is "personal"; revealing that having children has strengthened his resolve to "fight the system" that's "threatening" the environment for future generations.

The Liberal Democrats would provide an extra £100m for a new phase of the Green Deal to help people cut their energy bills, if they form part of the next government, Ed Davey tells conference. He says there will be a major tax cut for energy efficiency in the party's pre-manifesto: "a 10-year council tax cut, of at least £100 a year, paid for by central government".

Ed Davey says his department's energy market reforms have fixed the "mess" left by Labour, and opened up competition in the sector to counter the "dominance" of the "Big Six". He pledges to deliver on his promise to halve the time it takes for customers to switch energy supplier.

Every major energy supplier is on course to halve the time taken to switch provider, Ed Davey tells the Lib Dem conference.

Energy Secretary Ed Davey says he would end the Conservatives' fracking "free for all".

"Voting blue will never get you green," says Ed Davey as he continues his attack on the Conservatives. Only the Lib Dems can continue continue the rise in renewable energy, he argues. He tells conference that the Lib Dems would ban coal-fired power stations from 2025 if it forms part of the next government.

Ed Davey hails the growth in renewable energy, in particular onshore wind. He claims the Conservatives don't like this and have been urging him to cap onshore wind, "but I've just said no" because it's vital for climate change and to keep energy bills down, he adds.

Ed Davey hails what he sees as "dramatic" Lib Dem achievements in government, including the pupil premium, increases in the personal income tax thresholds and pensions reforms. The Lib Dems are also delivering real change in energy markets, Mr Davey says, because "we are outsiders, on the side of the people and not vested interests".

Ed Davey says being in power has made it harder to convince voters that the party is still the same "disruptive, insurgent force of politics". We've got to shout much louder about our role in spreading opportunity for all, he tells activists.

Energy Secretary Ed Davey is kicking off this afternoon's conference session with a speech. He says Nick Clegg has broken the "red/blue monopoly" on power after entering into coalition government. Mr Davey says the Lib Dems' "fair tax policy" is the biggest achievement of the parliament - and accuses the Conservatives of trying to claim it as their own.
