Well this is part of the whole thing that I’m looking at in relation to air quality, and you’ll be aware that local authorities obviously have duties under the local air quality management regime, and I know in certain areas I’ve been lobbied by Assembly Members, very early in the portfolio, around particular areas in particular local authorities. What I’ve done is ask officials to monitor local authorities very carefully, to make sure they are fulfilling their duties to produce an air quality action plan, so that we can have a look at what specific measures each of them are doing, and obviously the scientific research that we’re getting now in relation to diesel will form part of that.
