Confirmed by the Senate, Nicholas Brady now can expect to be sworn in as Treasury secretary within days so he can start work promptly at a meeting with international finance ministers next week.

Though a ceremony for the oath of office was not scheduled immediately after Brady's Senate approval Wednesday, the Wall Street executive told lawmakers in his confirmation hearing that he planned to fly to Berlin for the meeting with the leaders of other industrialized nations.Brady, co-chairman and managing director of the Dillon Read & Co. investment banking firm, will be following closely in the policy footsteps of James Baker, who resigned as President Reagan's second Treasury secretary to lead the White House campaign of his close friend, Vice President George Bush.
