NO2ID

If you have an MP that supports the governments ID plan and justifies his position by quoting the government propaganda that claims that 80% of the public are in favour of it (the ID plan).

Here is a way to disprove the '80% in favour of ID' claim, and after having successfully done so you can ask your pro ID MP to revise his position. And if the survey suggests the ID plan has extreme unpopularity
within a pro ID MPs constituency, then the MP will be reminded his chances of re-election will be reduced when his constituents discover he supported the hated ID legislation they are having forced onto them!

Randomly select a road in his constitiuency(sticking a pin in a map is as good a way as any).

Then take a copy of the no2id petition to all the properties in that randomly selected road, explain what the governments ID plan really involves and if they disagree with it, ask would they be prepared to sign the petition to say so.

If you can get 80% of the roads properties to sign against the ID plan
you have proof that 80% of a randomly selected section of people within your MPs constitiuency oppose the ID plan. Which is the exact opposite of the level of support the government claims it has (you may get 100% to sign against it which is even better)
Either way the point is made, and the random surveys signed petition is proof.
You then send a copy of the signed survey petition to your MP with a letter explaining why you carried out the random survey, and how it was done, listing the name of the road chosen, the total number of properties in it and the percentage of properties opposing ,supporting or neutral to the issue, and the conclusion (what it proved).

This will be convincing as an investigation into the governments claim of such high support for it's ID card plan. And will be feasible for any individual to carry out alone as it involves a relatively small number of people to contact.
(although to explain in detail the most disturbing contents of the governments draft ID bill can take a little while) but guaranteed to convince any sane person to oppose it (the ID plan).

Then all you have to do is present the evidence of your survey to your pro ID MP (in writing or by taking it to him in person).

Doing that (if it works) would certainly make your MP think. However, it is far from the proof you claim, because people in a single road are not going to be a representative sample, and because people you have spoken to about it are not in the same state of opinion as the 50,000 or so in his constituency you haven't spoken to, and because (as MPs well know), quite a lot of people will sign anything just to make you shut up and go away. Mich better to devote the same effort to engaging willing opponents form all over the constituency each to contact the MP, councillors, local newspapers and other opinion formers.

Good idea, but an easier way is to simply point him at the recent ICM poll which shows 43% are against:
