Suddenly, people south of the border have woken up to the possibility of an independent Scotland.
The Yes campaign have edged two points in front of the No camp for the first time, according to a YouGov poll for the Sunday Times.
Of course, this is well within the margin of error but what is painfully clear is that the vote is on a knife edge.
Westminster has been shocked out of its complacency. People living in England and Wales have suddenly realised what the Scots have known for some time: support for independence is growing.
Alex Salmond's Yes Campaign has been given a significant boost
You can almost hear the frustration in the voice of Better Together leader, Alistair Darling, who has put out a statement to say: 'These polls can and must now serve as a wake-up call to anyone who thought the referendum result was a foregone conclusion. It never was.'
After spending the last week in Scotland, the poll came as less of a surprise to me. It is clear that the momentum is with the Yes campaign.
Voters who were previously undecided are switching to Alex Salmond's camp at twice the rate of Mr Darling's, according to YouGov.
The difficulty for the No campaign, is how to respond.
Alistair Darling says it is clear the vote is not a 'foregone conclusion'
A No10 source has said the Prime Minister 'will strain every sinew in the coming days to make the case for a No vote.'
Some would argue that the less David Cameron does the better, (don't forget Scots elected only one Tory MP to Westminster at the last election.)
Labour also have big questions to answer. The YouGov poll shows that 35% of Labour voters now back independence, compared to 18% a month ago.
Ed Miliband is in the Mail on Sunday warning that there could be border controls if Scotland goes independent.
Scaremongering tactics or is there a grain of truth in it?
The reality is, that if an independent Scotland had a different immigration policy to the rest of the UK, border checks could happen.
But there is one card that Better Together still have close to their chest.
When I was in Scotland, several voters currently on the fence told me that more devolution could convince them to stay in the Union.
They explained they were frustrated that Westminster parties had refused to spell out in detail what would be on the table in the event of a No vote.
With the polls showing the result is now on a knife edge, that could happen sooner rather than later.
According to reports, the people of Scotland will be offered the chance to create a federal future for their own country before next year's general election.
A senior government minister told the Observer the announcement will be made within days.
