Obvously, I say this in jest

In this BBC article we find that:

Mr Vaz said it would be "catastrophic" if Britain voted no to the treaty [on the Eu constitution] and all the other states voted yes.

Also in the same article it is argued that the government should be more honest about the EU project and admit that it is mainly a political project and not as economic as we have been led to believe. A kind of hey, ok, we'll start telling the truth now move.

This is just a cynical ploy to cash in on the disenchantment felt by the electorate with politics and politicians. They are hoping that less people will be bothered to get out and vote on purely political matters (the what for's, why bother's and they'll do whatever they want anyhow's may possibly choose to stay in bed instead).

That way a NO vote can be discredited because only a tiny minority of voters bothered to get involved.
