Nicola Sturgeon said it would be "unsustainable” for Theresa May to continue blocking a second vote
She insisted she already had a mandate based on last year’s Holyrood election, reinforced with a Scottish Parliament ballot in which the SNP and Greens backed breaking up the UK.
But Ms Sturgeon signalled she was willing to delay holding a referendum beyond her preferred deadline of spring 2019 if the Brexit process was still underway.
Tory leader Ruth Davidson dismissed the event “a tired manifesto launch” and said Ms Sturgeon had failed to give Scots “single, positive reason for voting for her party.”
Unveiling the blueprint in Perth, the SNP leader denied that losing any of its 56 Westminster seats in next week’s general election would weaken her hand.
She also brushed off suggestions she was becoming a divisive figure after no image of her appeared on its front page.
Other keynote policies included £118 billion spending splurge, which Ms Sturgeon claimed was possible without widespread tax increases, and immigration policy being devolved to Holyrood.
Nicola claimed a SNP victory will seal a “triple lock” on another referendum
In these circumstances, any continued Tory attempts to block Scotland having a choice – when the time is right and the options are clear – would be democratically unsustainable.

She argued that there must be a rerun of the 2014 plebiscite because “there is just too much at stake for Brexit simply to be imposed on Scotland”.
Ms Sturgeon said: “If the SNP wins a majority of Scottish seats in this election, that will further reinforce our mandate.
“In these circumstances, any continued Tory attempts to block Scotland having a choice – when the time is right and the options are clear – would be democratically unsustainable.”
Ms Sturgeon added: “That is why I believe so strongly that at the end of the Brexit process – not now, but when the terms of the deal are known – Scotland must have a choice about our future; a choice between following the UK down the Brexit path or becoming an independent country.”
Nicola failed to spell out how she would overcome Theresa's veto in a Tory dominated Commons
The SNP leader announced in March that she wanted a second referendum between autumn 2018 and spring 2019 to give Scots a choice between Brexit in the UK and pro-EU independence.
She later backtracked after the Prime Minister ruled out that timescale, declaring “Now is not the time”.
The Tory manifesto added further hurdles agrued there could be no vote until there is demonstrable “public consent” for it and only after the Brexit process had “played out”.
Scottish Tory leader Ruth Davidson and Scottish Secretary David Mundell have both suggested this could run beyond the next Holyrood election in 2021.
Speaking at Perth Concert Hall Ms Sturgeon added: “The key point of principle for me is clarity at the end of the process which allows people to make a genuinely informed choice about the future of our country.”
She also repeated her claim she wanted to secure a place in divorce talks with the EU after her plan for a bespoke deal to keep Scotland in the single market was “brushed aside” by Mrs May.
The First Minister insisted: “Now, more than ever, it is vital to have strong SNP voices standing up for Scotland at Westminster.”
She claimed a vote for her party would “strengthen Scotland’s hand against Tory cuts” and also help protect against an “extreme Brexit”.
Repeated polls show voters do not want a second vote before Brexit is complete, and recent surveys support for independence has fallen to below 45 per cent.
The SNP’s popularity has fallen to as low as 41 per cent, from a high of 55 per cent in April 2015, the month before the SNP “tsunami” in the Westminster elections.
Ms Sturgeon barely mentioned Labour, other than warning a vote for her rivals on June 8 increased the chance of Tory MPs being elected in Scotland.
She criticsed the Conservatives for their “assault on social security”, claiming it amounted to an attack on the poor, disabled and vulnerable.
Ruth Davidson accused Nicola of fooling people by trying to ignore independence in her speech
Ms Sturgeon also confirmed support for a 50p top tax rate, but only if it was UK-wide.
She also said Nationalist MPs would support extra NHS spending across the UK that would increase the budget in Scotland by an extra £1billion over the next five years.
The manifesto also included a pledge to lift the freeze on benefits and abolish the two-child cap and the so-called “rape clause”.
The First Minister also indicated that she would lift the 1 per cent cap on public sector pay rises after she was confronted by nurse Claire Austin during a TV debate.
Unlike the SNP’s 2015 and 2016 manifestos, the new manifesto does not feature the party leader on its cover.
Instead, there are 10 pictures of babies and young children.
Ms Sturgeon denied she was becoming a more divisive figure adding: “The baby is much cuter than me.”
Ms Davidson said: “Nicola Sturgeon tried her usual trick today of trying to ignore independence in her speech but making sure she’s pushing for it in her manifesto. Nobody is fooled any more.

SNP leader Nicola Sturgeon stops for an ice cream after making an election campaign visit to Scottish Gas HQ in Granton, Edinburgh
“Strip away the bluster and it’s written down in black and white – she wants to drag Scotland back to another referendum by as early as next autumn.
“That would cost jobs, risk our economy, and distract us all from the real job in hand – improving our schools and public services.
“This was a tired manifesto launch by a First Minister who has failed in this campaign to give people a single, positive reason for voting for her party.”
Scottish Labour leader Kezia Dugdale said: “Nicola Sturgeon has once again confirmed that her number one priority in this election is her plan for another unwanted and divisive independence referendum.
“It is clearer than ever that the majority of Scots who don’t want another divisive independence referendum need to send Nicola Sturgeon a message that she should focus on the day job.”
Scottish Liberal Democrat leader Willie Rennie added: “The SNP must think we are stupid.
“They barely mentioned independence today but we know independence will be their top priority once the election is over.”
