uk-Ireland double taxation

I'm retired English domiciled and tax- resident in Ireland. From 2008 the law has been changed so that my UK investment income is taxed in ireland on a remittance basis. Previously under the Double taxation treaty it was taxed in Ireland whether remitted or not, but was completely exempt from tax in the UK.
Somewhere on the web I saw a reference to a snag: the Uk government is nowgoing to impose tax if the income is NOT remitted to Ireland.
Anyone know anything about this?
