Johann Lamont said the new powers were a chance to end the "politics of grievance" where Scots look at a problem and blame someone else.
"It is possible to vote No on 18 September and also say you are voting for change, for more powers for the Scottish Parliament," Johann Lamont says.
Scottish Labour leader Johann Lamont speaks first on the steps of Dynamic Earth in Edinburgh. She says she is "delighted" to endorse the delivery plan set out by Gordon Brown that will give certainty of more powers to the Scottish Parliament.

We are expecting to hear the Scottish party leaders set out their timetable here at Dynamic Earth in Edinburgh
George Shepard: Could someone please ask the No camp, why was the choice of Devo Max removed from the ballot paper? Was it removed because UK Government did not want to give any new powers, as it would appear that that is what they are trying to promote now.
Duncan Grant: Why no regular comment on why 600,000 Scots living in England get no vote even if only here for a short while. This is a constitutional scandal. An immigrant who has been in Scotland for a few months can vote even if they can't speak English. I along with most others would vote no!
John, Kirkcaldy: All very well saying they are are going to give us "home rule" (when they could have had that option on the ballot paper in the first place) but do we get another shot at independence if we don't like their proposals? And what is the trade off?
Labour's Douglas Alexander told Good Morning Scotland: "What all three political parties are committing to is actually what most people in Scotland want. We want progress for Scotland but we don't want to break up the United Kingdom."
Blair Jenkins, chief executive of the Yes campaign, told Good Morning Scotland: "The power elite at Westminster seem to have been taken completely by surprise by the fact that more and more people are moving towards a Yes vote.
"People today looking at this repackaging of what's already out there in terms of offers will be mightily unimpressed.
"We know that these powers that the three parties put forward earlier this year, and which contradict each other to quite a large degree, are not sufficient. They don't give Scotland the governments we vote for, they don't give us the job-creating powers we need and they don't give us the powers to protect our vital public services, including the NHS."
Labour MP Douglas Alexander, who is campaigning for a No vote told BBC Scotland's Good Morning Scotland programme: "We all want the best for Scotland, on both sides of the argument, the real question for 18 September is 'what kind of change do we want for our nation?'
"What is being confirmed today is that a vote for No will deliver, on a very quick timetable, the kind of changes I think most of us in Scotland want to see."
The Daily Record leads with former Prime Minister Gordon Brown's speech where he detailed a timetable of extra powers to be devolved to Scotland in the event of a "No" vote.
The Scotsman's runs with news that the latest polls show that support for the Yes and Better Together campaigns are now too close for a clear prediction of the 18 September vote.
Angus Robertson, the SNP's leader at Westminster told the Today programme: "What the three UK parties are proposing does not give us control over all corporation, over all income tax, over oil taxation, over all our job powers, the ability to get rid of Trident, to stop our troops being sent into illegal wars.
"If the three UK parties had been serious they would have done this a long time ago. If Gordon Brown really cared about this he would have done it as prime minister. If the Tories cared about it would have been in the Queen's speech. This is a cynical last minute offer."
Stuart MacPherson tweets:, external Why promise more power but not announce it until October. Truth is all 3 uk can't agree on them. Would have voted for max devo #bbcindyref
David Wardrope tweets:, external #bbcindyref Enough with the more powers line! The 3 UK parties have different ideas on powers for Scotland and can't agree on common list.

Labour MP Jim Murphy, a former Scottish Secretary, told the Today programme: "We want to be really clear that if people vote No, they are not voting for No change. Change is coming.
"As a consequence of what Gordon Brown and the Labour party announced last night, agreed with the other parties, who seem to support it, the day after a No vote the House of Commons will have a motion tabled setting out an approach that will bring new and significant powers to the Scottish Parliament at remarkable speed."
Today's edition of the Scottish Sun runs with the headline "Grab a Granny" with the paper claiming that Alex Salmond is asking pro-independence supporters voters to convince their elderly relatives to vote "Yes" on 18 September.
Elsewhere the Scottish Daily Mail leads with news that £2bn has been wiped of the value of Scottish firms following uncertainty on the markets over the outcome of the independence vote.
The SNP's Westminster leader Angus Robertson told BBC Radio Four's Today programme: "The big news of the day isn't the reheating of an announcement by Gordon Brown and his allies in the Conservative party, the big news is that the momentum continues to be with the Yes campaign.
"The Yes side is up six points, the No side is down six. We are seeing massive numbers of voters, especially Labour voters, switching to the Yes side.
"In contrast we have total panic and desperation from the No side, offering a cynical bribe which is utterly transparent to voters in Scotland."

If you are talking, as the Unionist parties now are, of a massive transfer of income tax powers so the Scottish Parliament has control over a substantial amount of the money it raises it is likely that other parts of the United Kingdom will demand the same.
The Northern Irish assembly have asked for tax-raising powers in the past, the Welsh may, parts of the UK who feel remote from London, whether in the south west or the north east, may well want the same.
Today the prism through which all this is being seen is whether it is enough to win the Scottish campaign. The next step I can tell you is the No campaign are going to do is say these new powers will allow them to guarantee absolutely that the NHS in Scotland could never be cut against the will of the Scottish people.

Downing Street source says Conservatives & Lib Dems are backing Labour's timetable but sticking to their own plans for more powers.

What is striking is that they have managed to forge this agreement under pressure of the polls, in a day or two and we may be seeing the biggest constitutional change in the United Kingdom, if Scotland does vote No and this ever actually happens, with precious little debate about it.
"Because those No parties have been forced to come together and try to hammer out some form of agreement about what they would do and when.
"The big change is really in that timetable. The plan of the government at Westminster had been to say 'Yes we will begin a process of consultation after a No vote but the actual process of legislation would come after a General Election.
"Now they are saying it starts the day after, and as Gordon Brown likes to promise 'you can get a draft law by Burns night in January'."
Blair McDougall from the Better Together campaign tells the BBC's Tim Reid there was an "absolute guarantee" that new powers would come to Scotland in the event of a "No" vote. He added that there has been a "real market reaction" to the prospect of the break-up of Britain. Blair Jenkins from the Yes Scotland campaign responded by saying the move by the pro-Union parties to offer more to Scotland was a "panic" measure. He added that it was the "same old stuff" and it was the power elite at Westminster thinking they "know what is right for us".

The news bulletins this morning should have been preceded with the announcement 'Do not adjust your set, we know that Gordon Brown is not the prime minister of the United Kingdom'.
"Because normally you would have expected David Cameron to make this sort of announcement but he was deemed to be too Tory and too English. Ed Miliband was deemed to be certainly too English and the latest polls show he is trusted as little as Mr Cameron in Scotland. Alistair Darling was damaged by the debates so Gordon Brown was reached for as the man who reaches the parts of Scotland others in the No campaign cannot reach.
