Do you live in Sunderland? Are your bags packed? Well, the Policy Exchange thinks that perhaps they should be.
In a report (pdf) in which it's sometimes hard to see where the serious thinking ends and the sheer provocation begins, the rightwing thinktank argues that it is unrealistic for "struggling" northern population centres like Sunderland, Bradford and Liverpool to become prosperous again.
Instead, it says - as covered in many papers today that millions more homes should be built in the south-east to make it easier for people to resettle there.
Apart from London, the Oxford and Cambridge areas should see huge building programmes to cater for the northern influx, the report says, adding:
It is time to stop pretending that there is a bright future for Sunderland and ask ourselves instead what we need to do to offer people in Sunderland better prospects.
The report has plenty of potential to embarrass David Cameron who, the Times points out, begins a tour of such destinations as Carlisle, Barrow-in-Furness, Morecambe and Liverpool today.
The Policy Exchange has close links with Cameron's party. Founded by the his education spokesman, Michael Gove, it is, the Mail says, "one of the Tories' favourite think-tanks".
Another of Cameron's ministers, Chris Grayling, has been swift to stress that the party disagrees with the report.
In an acknowledgment of how this idea sounds to millions of Britons, the report's co-author, Tim Leunig, from the London School of Economics, says: "No doubt some people will claim that these proposals are unworkable, unreasonable and perhaps plain barmy."
Barmy? That's a strong word, especially as the Policy Exchange, and similar institutions are supposedly there to think the unthinkable. But you could place a heavy bet that the report's findings won't be featuring in the next Conservative manifesto.
