The specific issue the Senator raised was that of tax harmonisation. This is an important matter. We have said we are not hostile to the process of tax harmonisation, but it is of such significance that it should continue to be dealt with on the basis of unanimity within the Council of Ministers. Senators will appreciate that, given that we have surrendered the monetary instruments, the fiscal instrument is important and close to sovereignty. I feel a sense of annoyance about this in the Convention because most of the arguments put forward for tax harmonisation by QMV are ill-considered and do not stand up to any critical test. I understand why some countries are making those arguments, but I cannot understand why others are doing so.
