No, I’m not talking about the latest poll – whatever it is. Another will be along in a minute and a percentage point here and there at this stage cannot be a cause for despair or for celebration. It’s abundantly clear that an important slice of the British public are still undecided about whether they’ll vote to stay in the EU or to leave and it is by no means certain how many voters, on either side, will actually get out of bed to cast their ballot.
