In a Memorandum addressed to the Queen, Lord Granville laid down the main principles of the new foreign policy. They were a distinct expression of Liberal ideas. "It was the duty and interest of a country such as Great Britain to encourage progress among all other nations. But for this purpose the foreign policy of Great Britain should be none the less marked by justice, moderation, and self-respect, and avoid any undue attempt to enforce her own ideas by hostile threats.... They did not attach to the expression 'non-intervention' the meaning implied by some who used it, viz., that diplomacy is become obsolete, and that it is unnecessary for this country to know or to take part in what passes in other countries.... With respect to the internal affairs of other countries, such as the establishment of Liberal institutions and the reduction of tariffs in which this country has an interest, H.M.'s representatives ought to be furnished with the views of H.M.'s Government ... but they should be instructed to press those views only when fitting opportunities occurred, and only when their advice and assistance would be welcome or be effectual.... With the countries which have adopted institutions similar in liberality to our own, it ought to be the endeavour of H.M.'s Government to cultivate the most intimate relations ... and also to exert its influence to dissuade other Powers from encroaching on their territory or attempting to subvert their institutions. Cases might occur in which the honour and good faith of this country would require that it should support such allies with more than merely friendly assurances."[273] This was the policy of the Government, composed partly of Whigs and {217} partly of Peelites, which replaced the short-lived Government of Lord Derby in 1852.
