asked the Minister of Health if he is aware of the anxiety which exists about pollution of the River Thames and the danger to health therein involved; and what action he is taking.

I am aware that conditions are unsatisfactory in certain parts of the river, and I am in close touch with the authorities concerned as to the different problems which arise. If the hon. Member would indicate which particular reaches of the river he has in mind I should be glad to make inquiries and to give him such information as I can.

Is the right hon. Gentleman prepared, in due course, to indicate whether any reaches above tide water are unsafe for bathing on health grounds?

If the hon. Member will indicate what particular reaches they are, I will make inquiries. At the moment I do not know.

Would the right hon. Gentleman consider giving a general warning to the public, covering the whole of the river above tide water?

No; I think that would frighten people unnecessarily.
