"We are all British and we should all have to play by the same rules."
"A country where people who play by the rules get on and those who don't, don't."
Michael Howard? Tony Blair? Both - Howard first, Blair second - and both speaking as they launched their campaigns this morning. Playing by the rules has become a fashionable dictum among both the main parties. It implies a tough approach to law and order, but it also hints at strict immigration controls. It says: We're inside, we're enjoying ourselves, you can join in, but only on our terms. You'll hear it again during this campaign.
