George Osborne says the Conservatives will honour pledges to hand more powers to Scotland - but says there must also be further devolution to the rest of the UK as well.

Labour is not being straight with the people over what is required to balance the nation's books, George Osborne says, whereas the Conservatives have been able "to take the people with us" by levelling with them about the scale of the challenge. The latest Treasury estimate is that a further £25bn of permanent spending cuts or taxes are needed to eliminate the deficit - but tax cuts are not the answer, he argues, insisting that country has not taxed too little but spent too much.

George Osborne is receiving lots of applause from party members. He says economic security is at the core of the Conservatives' offering. He says the party would ring-fence banks' high street operations from "riskier" investment arms. Now some comment on the deficit, which although halved is "still too high". Mr Osborne pledges the Conservatives will continue to eliminate it and run "surpluses" in future years.

David Cameron is among the audience watching the chancellor's speech.

Some praise from George Osborne for his leader, David Cameron, who he says offers "real leadership". The chancellor goes on to talk about the choices the country faces - "the past or the future". The Conservatives choose the latter, he adds.

George Osborne says Labour's policies are "built on sand" - arguing that the NHS cannot be properly funded unless the economy is working properly. It's only because the government took difficult spending decisions that it was able to ring-fence the NHS budget in this parliament, he says, and insists the Conservatives are the "real party of the NHS".

Mr Osborne mocks Labour leader Ed Miliband's speech, which he says "was so forgettable, he forgot it himself" - prompting laughter. Forgetting to mention the deficit was not "some hapless mistake" but "disqualification for the high office he seeks", he asserts.

Global events have an impact on both national and economic security, the chancellor tells the hall. He says new technologies are "fundamentally shaking up" the traditional way of doing things, which is "exciting" but also "unsettling". It brings intense competition that spells "rapid decline" for any sector or country that "fails to keep up". But the next Conservative government will provide these answers, Mr Osborne promises.

George Osborne says he is "humbled" by how much more there is to do - to reduce the debt and support businesses - and resolves to "finish the job we have started". He says Britain cannot "ease up" and cites other European countries which risk returning for crisis for taking their foot off the pedal. He also cites the international situation, including Russia, the Ebola outbreak and a generational struggle against "barbaric" Islamic State militants.

Mr Osborne says the Conservatives "held our nerve" despite criticisms of their economic plan - and points out that Britain is now the "fastest-growing most job-creating, most deficit-reducing country of any major advanced economy in the word". He adds: "Our long-term economic plan is working."

George Osborne cites the Golden Boys statue in Birmingham, near the conference hall, which he says is an image that captures the "golden age of our country... when we faced the future with confidence". I want us to be that Britain, he tells the hall, and says it can be the most prosperous, dynamic and creative country in the world.

Enter, stage left, Chancellor George Osborne, who receives a standing ovation from the hall.

Lord Jones appeals to politicians of all persuasions not to "mess with our economy" which is "too precious to be gambled with on the alter of experiment or some tribal ideology".

Lord Jones quotes William Gladstone's words : "You don't set the poor free by giving the money; you set the poor free by giving them an education." He criticises national insurance contributions (NICs) as his "pet hate", and says the chancellor is "quite right" to describe it as a "jobs tax". He hopes all parties will commit in their manifestos to completing abolishing NICs, and linking their abolition to "training more and young people".
