asked the Minister of Transport if he will consider appointing a committee to consider the advisability of constructing a lock above the Pool, so that the River Thames can be maintained at a constant level and traffic could proceed independent of the tide?

I have brought the hon. and gallant Member's question to the notice of the Port of London Authority, but I do not propose to appoint a committee to consider any scheme such as he suggests, of which the effect, in my view, would be rather to impede than to facilitate traffic.
