Financial Transaction Tax and Economic and Monetary Union

Does the proposal not expose the beguiling attraction of allowing enhanced co-operation as a gesture of good will to our European partners, when in fact it is a trap enabling them to exercise powers through qualified majority voting, without our participation, which then creates obligations in relation to our own financial transactions, even though they might be taking place outside the EU? My right hon. Friend expresses support for co-operation between free, sovereign states in their tax affairs, but that is not what we are talking about here, because enhanced co-operation is likely to result in obligations that are enforceable in European Community law, even though we have not had a chance to vote on them.
