asked the Minister of Agriculture, Fisheries and Food if he is aware that in New Zealand there is an Act prohibiting the sale of rabbit carcases and skins, thus removing the commercial outlook and enabling the problem to be dealt with solely as a pest and if he will consider similar legislation to deal with rabbits in this country.

I have all aspects of the rabbit problem under consideration, including experience in New Zealand, though in some ways circumstances in the two countries are different.

asked the Parliamentary Secretary to the Ministry of Education what is the overall cost of divisional executives; and how many of these are in being in England and Wales.

I estimate the total administrative costs of divisional executives at somewhere between £3 million and £4 million a year. There are at present 204 divisional executives, including the councils of 44 excepted districts.

asked the Minister of Housing and Local Government to what extent the Advisory Council for Wales and Monmouthshire needs his consent before altering its constitution; and on how many occasions since its formation such consent has been sought.

The constitution of the Council for Wales and Monmouthshire has always been a matter for the Government to determine. Thus the second part of the Question does not arise.

asked the Minister of Housing and Local Government whether he will now remove from official documents and records relating to Wales the additional words and Monmouthshire, since Monmouthshire is included in the term Wales.

I do not think that such a course would be consistent with various statutory provisions relating to Monmouthshire.

asked the Minister of Transport and Civil Aviation if he will, in conjunction with the London County Council, consider the construction of underpasses at the road junctions at Camberwell Green, St. George's Circus, the south end of Vauxhall Bridge, Brixton Hill with Effra Road and Acre Lane, Camberwell New Road with Kennington Park Road and Brixton Road, New Cross Road with Queens Road and Old Kent Road, Clapham Road with Stockwell Road and South Lambeth Road, Lambeth Road with Kennington Road. Lambeth Road with St. George's Road, Kensington Road with Warwick Road and Holland Road, W.8, Holloway Road with Parkhurst Road and Seven Sisters Road, and Seven Sisters Road with Green Lanes.

It is my policy and that of the London County Council, when considering the major improvement of important road junctions, to examine the justification for and practicability of constructing underpasses or fly-overs. This policy will apply to the twelve junctions referred to when layouts for their ultimate improvement are being considered.

asked the Minister of Pensions and National Insurance whether he will make a statement on reciprocal arrangements on social security with Norway.

I am glad to be able to tell the House that on Thursday, 25th July, during a visit to London of the Norwegian Minister of Social Affairs, my right hon. and learned Friend, the Foreign Secretary and I signed an agreement on social security with Norway.The agreement will cover the benefits provided by the National Insurance, Industrial Injuries Insurance, Family Allowances and National Assistance schemes in this country and the corresponding benefits in Norway, and the Norwegian health services will be made available to British nationals, including tourists.The agreement will come into force after it has been ratified, when a further announcement will be made.

asked the Secretary of State for Scotland what changes his health department has made in treatment for the prevention and cure in Scotland of poliomyelitis; when a change was made; why it was made; and what success the new treatment has had and is having in Scotland.

In May and June, 1956, some 5,000 Scottish children received one injection and 30,000 two injections of a British vaccine. Vaccination was discontinued at the end of June when the period of prevalence was likely to begin.When vaccination was resumed in 1957 the decision was made to continue it throughout the year. This change followed advice given to the Minister of Health and myself by the Health Service Councils.I am sending to the hon. Member a copy of a Report by the Medical Research Council which was published last month.
