So Big Ben strikes ten on May 6th
Will this mark the start of a change of government?
The polls will close. Then all the TV and radio news channels will announce the first details of the exit poll that MORI have been carrying out throughout the day and which will have been processed and analysed by Professors Curice, Thrasher and Rallings.
Over the next few hours results from about half the constituencies – the rest will be counted on the Friday.
At what stage will the picture become clear – or could, after all, we find ourselves in hung parliament territory and the nail-biting will continue?
What is extraordinary is that we have only had one change of government in the 31 years since Mrs Thatcher’s famous victory in May 1979.
It’s only a few weeks away.
