And for that reason it’s essential that we plan transport holistically and that we do not see transport modes in isolation but as part of an overall package of responses to what is an increasingly mobile world. I think the figure, if we were to maximise the capacity on the metro—the maximum figure that we could remove from the M4 would be about 4 per cent of existing traffic. I’ll correct myself if that’s wrong. But, the fact is that we need to ensure that the M4 is fit for purpose now that the tolls are going to be removed. The M4 was built at a time when it was a bypass rather than a motorway. It requires urgent work. But I await the outcome of the public local inquiry before making a decision.
