asked the Secretary of State for the Colonies when the Kenya Government intends to bring its practice, with regard to the remission of prison sentences, into line with that obtaining in this country.

This matter is under consideration in connection with a Bill providing for a new Prison Ordinance which is at present being prepared and which the Kenya Government hope to intsroduce into the Legislative Council later this year.

asked the Secretary of State for the Home Department whether, pending consideration of the Drew Report proposals for a breathalyser test for drunken drivers, he will immediately draw the attention of all police forces to the merits of the method of urine alcohol tests at present used successfully by the Glasgow police.

Chief officers of police are already aware of the value of urine alcohol tests. These tests have been widely used for a number of years.

asked the Secretary of State for the Home Department if he will make a statement as to the bringing into force of Sections 21 to 23 of the Legal Aid and Advice Act, 1949.

After consultation with those concerned I have made an Order bringing into force Sections 21 to 23 of the Legal Aid and Advice Act, 1949, on 14th March, 1960. I have also made new sets of rules and regulations prescribing scales of payment to counsel and solicitors who give legal aid in criminal cases in the various courts. These will take effect in respect of certificates granted, or defences undertaken at the request of a judge or chairman of a court, on and after 14th March, 1960. Copies of the various instruments are available in the Library.

asked the Minister of Housing and Local Government and Minister for Welsh Affairs whether he proposes to make a preservation order for the Central Hotel, Cambridge, in view of the fact that it was listed by the Royal Commission on Ancient Monuments as specially worthy of preservation.

I informed the Cambridgeshire County Council last April that I did not propose to make a preservation order. I have considered the matter further in the light of what the Royal Commission has said, and of all other relevant factors, but I adhere to my original view.

asked the Minister of Transport if, in the light of experience gained, he is satisfied with the cross-sectional design of M.1; and whether he will consider the provision of a kerb to the edge of the highway.

A careful study is being made of the lessons to be learnt from M.1. It is too soon to reach final conclusions. For safety reasons it is not desirable to provide raised kerbs at the edges of the carriageway where they may be struck by fast-moving vehicles. Kerbs to mark the outer edge of the hard shoulders would interfere with drainage, but other means of defining this edge are being considered.

asked the Minister of Transport if he will consider making provision for the improvement of the hard shoulder to the M.1, so that vehicles using it may do so without getting into difficulty.

The hard shoulders of grass construction on M.1 have suffered considerable damage through heavy usage while still immature. I am examining urgently the measures which might be taken to strengthen them.

asked the Minister of Transport whether he will issue statutory regulations requiring all lorries to be fitted with four rear lights on the four extreme points on the back of the lorry, as is the practice in the United States of America and many European countries.

In the United States of America and certain other countries large enclosed lorries are used much more extensively than in this country, where the size and shape of lorries and their loads vary very considerably. It would therefore be difficult if not impossible to light the upper extremities of them all, but I will have my hon. Friend's suggestion examined.

asked the Minister of Transport whether he has yet studied the laboratory tests described in the Drew Report; and if, when preparing legislation on the subject, he will bear in mind the possibility that these tests underrate the risks in real road conditions, in view of the fact that faults made on an empty dummy road devoid of risks would be multiplied on a real road with other traffic and the additional complication of dazzling lights.

I have nothing at the moment to add to the Answers which I

asked the Minister of Labour what proposals he has for building a new employment exchange in the Metropolitan Borough of Southwark; and if he will state the location of the proposed site, how long the site has been allocated for such purpose, and when it is proposed to commence building.

asked the Minister of Transport whether, in view of the deleterious effects of diesel fumes, particularly on people suffering from bronchitis, he will introduce legislation to check this form of air pollution by vehicles.

The law already provides that every motor vehicle must be so constructed that no avoidable smoke or visible vapour is emitted. The law also makes it an offence to emit smoke or vapour if this causes or is likely to cause damage to property or injury to any person or is likely to cause danger to any person on a road.

asked the Minister of Labour the average numbers of severely disabled persons employed by Remploy Limited in each of the last five years.

The information asked for is as follows:

A new employment exchange in the Metropolitan Borough of Southwark is to be provided as part of a larger scheme which the Ministry of Works has in hand for the rehousing of several Government Departments. The new building will be erected on a site in Keyworth Street which was acquired in 1939 and it is expected that the work will commence within the next month or so.

asked the Minister of Transport if he will make a statement on the Report of the Committee on the Safety of Nuclear-powered Merchant Ships.

The Report, which has now been issued as a Command Paper (Cmnd. 958), contains a comprehensive survey of the measures required nationally and internationally to enable nuclear-powered merchant ships to be operated with safety, particularly in the initial stages of development. The Committee's recommendations will provide an excellent basis for legislation in due course and meanwhile for international discussion at the Conference on Safety of Life at Sea which is to be held in London next May. They will also be discussed fully by my Department with the interests and authorities in this country who are concerned.I should like to take this opportunity of thanking the members of the Committee for the great help they gave in considering this complicated and difficult problem.
