There is no chance of Test Matches being moved from Lord’s. Whether we like it or not, it is the prestige venue and where the ECB is based.
It is a bit irritating when Lord’s gets two Tests in years when more than one team is on tour but I suppose they all want to play at the venue.
It is rather like St Andrews in golf. It has the history and prestige and the Royal and Ancient is based there, so it will always host The Open (far more often than any other course does). But it is the easiest and possibly least good course on the rota and (rather like the Rose Bowl) not straightforward to get to via public transport.
The Open ought to be moved or at least played there a lot less often but it will never happen.
