A few days ago I posted the following on this blog.
Today the local newspaper has a front page story on the issue. Apparently the developer is close to signing an agreement with a supermarket and then will submit a full planning application to Tunbridge Wells Borough Council - hopefully in October. The line the developer is promoting is that once the supermarket has signed up other organisations (including an hotel operator) will follow suite.
Time will tell, but the Council should be working on the preparation of a compulsory purchase order and dusting down the plan, prepared at his own cost, of the Leader of the Council.
