Conservative Back-Benchers, I hasten to add, not Liberal Democrat ones. The Prime Minister's response to that was pathetic, even when what was at stake was a question of us sticking to the law. What kind of confidence can we have that an EU referendum would be fought on a fair basis unless these kinds of guarantee are written into the Bill?
I come back to the case of our car industry outside the EU. Unless we can negotiate a special deal with our partners there will be a 10% tariff on cars that are made in Britain. That will have a devastating impact on jobs in the British car industry. We cannot take these decisions lightly. We have to think about what we would be able to negotiate.
We should also have a realistic assessment of what we will be able to negotiate. Many people think that we would have the whip hand in any such negotiations were we outside the EU. I think that it was my noble friend Lord Davies who said that, in fact, that is not the case. We have to face the fact—and people are hard-headed about economic matters—that our exports to the single market account for between 40% and 50% of our total exports, however we calculate it. The rest of the single market’s exports to us account for about 8% of its exports, so if we are just looking at this in terms of the balance of power in that negotiation, it is not an attractive one from the prospect of jobs and growth in Britain.
In conclusion, if the noble Lord, Lord Dobbs, is not prepared to accept this amendment, is he certain what his alternative to EU membership would entail? How would he go about making sure that the referendum was fought on a fair basis? If we cannot have this fair assessment then, frankly, the Bill is as I described it at Second Reading: an invitation to buy a pig in a poke.
