A referendum on the EU constitution?

[ewx]

Apparently Peter Hain thinks not. As such, The Economist remarks:

Given that the government has called 34 referendums (mostly about mayors) since 1997, it seems odd to draw the line at the biggest constitutional issue to have come before the country for decades.

Referendums are like security reviews (or is it the other way around?); if they don't fail occasionally they you don't know that they're doing their job.
