Nicola Sturgeon is going to the town where ‘Braveheart’ William Wallace won a historic battle against the English, to launch a new drive for a second independence referendum.
The Scottish First Minister, who knows she cannot demand another vote without being sure of a win, is triggering what she calls the "biggest ever political listening exercise" to convince Scottish voters a referendum is needed.
At the event in Stirling, Ms Sturgeon was to say "seismic changes" following the UK’s decision to leave the EU will have a "deep impact" on Scotland that needs to now be addressed.
It was at the Battle of Stirling Bridge in September 1297 that Wallace defeated the army of Edward I despite being hugely outnumbered.
Ms Sturgeon’s speech comes nearly two years on from the September 2014 referendum which saw Scots vote by 55% to 45% in favour or remaining in the UK.
The SNP Leader was to say: "The UK that existed before June 23 has fundamentally changed.
"The debate now is whether we should go forward, protecting our place as a European nation or go backwards, under a Tory government with very different priorities.
"And while we will pursue all options to protect our interests, the debate must include an examination of independence in what are profoundly changed circumstances.
"To ensure that the voice of everyone in Scotland is heard in these changed times, I am today launching Scotland's biggest ever political listening exercise - a new conversation and a new debate for these new times."
After this year’s Brexit vote Ms Sturgeon warned that a second independence referendum was "highly likely" and she has tasked the Scottish Government to draw up legislation to pave the way for another ballot.
Prime Minister Theresa May has signalled she is against the idea and Labour, Tories and Liberal Democrats in Scotland have all vowed to oppose the legislation. The minority SNP administration could see a referendum Bill passed if it is backed by the Scottish Greens.
Labour MSP James Kelly said: "It is disappointing that, days before laying a legislative agenda before the most powerful Scottish Parliament ever, the SNP are determined to drag us back to the arguments of the past."
Scottish Liberal Democrat leader Willie Rennie claimed Ms Sturgeon had already decided independence was the answer to Brexit.
He added: "She is therefore only pretending to listen. With the chaos of Brexit we do not need further chaos with the threat of independence."
Ms Sturgeon was cheered by supporters after announcing plans for an initiative to boost support for leaving the UK at her party conference in March.
Amid turmoil caused by the Brexit vote, Labour in-fighting, and the Tories remaining in power at Westminster, the SNP believes the political moment may be right to look again at Scotland's future.
But the SNP’s vision suffered a blow after it emerged Scotland's public spending deficit stood at £15 billion in the past financial year amid plummeting oil revenues, which were supposed to have been the economic foundation of independence.
