Scottish Secretary Alistair Carmichael is introducing an emergency debate on UK federalism. It's less than well-attended. Mr Carmichael jokes that his audience on Sunday morning at conference was "really quite full" in comparison.

Looking ahead to Nick Clegg's speech, expected to start at about 13.15 BST, aides say he'll be wearing a suit and tie and will use an autocue. Much was made of Mr Clegg's more casual attire earlier this week - with commentators engaged in debate as to whether the Lib Dem leader was wearing chinos or jeans for his Q&A with party activists.

At a fringe meeting last night, there were testy exchanges between TUC General Secretary Frances O'Grady and Danny Alexander. Ms O'Grady laid into the coalition's "unfair" public sector pay freeze and claimed low-paid workers had gained nothing from the Lib Dems' cherished policy of raising personal allowances because their benefits had also been cut. The Treasury Secretary called her analysis "economic nonsense" and said unions should be politically neutral - and stop funding campaigns to oust Lib Dem MPs. He did, however, back the unions' fight against Conservative plans to stop them taking subscription fees directly from civil servants' pay packets.

Back in the conference hall, Party President Tim Farron is responding to a raft of questions from party members, including on gender and ethnicity balance in the Federal Executive (FE). The FE is responsible for directing, co-ordinating, and implementing the work of the Federal Party.

Speaking to the BBC earlier, Lib Dem Care Minister Norman Lamb said the introduction of maximum waiting times for mental health patients in England will be "a watershed moment...a historic moment". He said the government's plans will "ensure genuine equality between mental and physical health". Mr Lamb also revealed that he has not "ruled out standing for the leadership" of the Liberal Democrats when Nick Clegg is no longer in the role - but stressed he doesn't want to "replace" the current leader.

In the meantime, there's plenty of business to be seen to by conference. There are a series of reports for activists to contend with, on diversity, gender balance and party matters including the governing Federal Executive and membership subscriptions. We're also expecting an "emergency debate" on UK federalism at 09.45 BST, and a discussion on creating a "more diverse" banking system. A Q&A on the environment will be led by MP Tessa Munt, followed by a debate on private rented tenants.

The Lib Dem leader has announced that waiting time targets for people with mental health problems in England will be introduced for the first time. Under the plans - which will cost £120m - young people with psychosis will be seen within 14 days for the first time, and suicidal patients are to get the same priority as those with suspected heart attacks. It is a coalition policy, not just a Lib Dem manifesto pledge - but advance extracts of the speech indicate Mr Clegg will promise to extend the money into the next parliament to introduce similar targets for other conditions such as bipolar and eating disorders.

Hello and welcome to our live coverage of the last day of the Lib Dem conference, which will climax in a keynote speech from Nick Clegg at 13.15 BST. Ahead of the speech, Mr Clegg has announced that mental health reform will be a "red line" for the Lib Dems in any future coalition negotiations. He is committed to delivering parity between mental and physical health services in England.
