Why no weekend medical emergency cover in Lewes?

I do not think it is acceptable that there is no medical emergency cover during the weekend in the county town of Lewes.

If you need to see a doctor, the two choices available are to ring 999 or travel to Uckfield Hospital and while Victoria Hospital is here, for which I collected for many years, surely it could be manned by one or two doctors between Friday and Monday.
