It may do, or it may not. As my right hon. and learned Friend Mr Clarke has said, there is no evidence to suggest that a single country would not behave in a good way. But there is absolutely no evidence that they will all behave in a good way; we simply do not know, because we have not yet had that conversation. Until we have had that debate and secured an agreement that similar rights will be granted to British citizens living in other EU countries, we should not move to allow every single EU national who lives here to continue doing so.
