He made clear, however, that ministers would be “led by the listener” to ensure that the audience did not miss out through a digital switchover.
“Most cars now have digital radio fitted as standard, it’s becoming much cheaper to buy a digital radio, they’re much more energy efficient and what we will do is we will keep this constantly under review,” Mr Vaizey told the Today programme.
“When we reach a certain target of listening on digital – and we’re very close to that target at the moment – we’ll take a view on what the appropriate next step will be.”
He said that the BBC itself may be inclined to “make their own decision about the future of FM” in coming years.
But he added: “I’ve always said that we have to be led by the listener and you will know better than anyone how passionate your listeners are about listening to the Today programme, to Radio 4, and we don’t want to do anything that would impinge in any way on listening to a programme like this.”
