Dr Singh's direction comes in the wake of Textile Minister Dayanidhi Maran and former telecom minister A Raja getting embroiled in the massive 2G scam, embarrassing the ruling United Progressive Alliance government considerably.
The letter states that the terms of the Code of Conduct details in respect of assets, liabilities, business interests, conduct and management of any other business and employment of spouse and dependents under a foreign government or organisation are required to be disclosed by the members of the Union Council of Ministers.

The paragraph 2 (a) states that, "After taking office, and so long as he remains in office, the Minister shall furnish annually by the 31st August to the Prime Minister, or the Chief Minister, as the case may be, a declaration regarding his assets and liabilities for the previous financial year".
The paragraph 2 (e) states that a minister should, "report the matter to the Prime Minister, or the Chief Minister as the case may be, if any member of his family sets up, or joins in the conduct and management of, any other business."
According to paragraph 3.2, "A Minister, including the Union Ministers, the Chief Ministers and other Ministers of State Governments/Union Territories, should not permit their spouse and dependents to accept employment under a Foreign Government, in India or abroad, or in a foreign organisation (including commercial concerns) without prior approval of the Prime Minister".
"Where the wife or a dependent of a Minister is already in such employment, the matter should be reported to the Prime Minister for decision whether the employment should or should not continue," it said.
"As a general rule, there should be total prohibition on employment with a Foreign Mission," it said.
