I support the notion of harmonising policy in a defined range of areas such as cross-border crime, in relation to the sort of criminal offences as a result of which people are prosecuted and in relation to the way in which people are prosecuted. This can be done by developing a joint prosecution service. This is a good thing and we should not be nervous about it. We need to develop the joint arrest warrant and the mutual recognition of arrest warrants and I appreciate that progress is being made in that regard. Equally, individual traditions, such as Ireland's common law past, should be recognised and acknowledged.
