On 25 May 1998, Putin was appointed First Deputy Chief of the Presidential Staff for the regions, in succession to Viktoriya Mitina; and, on 15 July, he was appointed head of the commission for the preparation of agreements on the delimitation of the power of the regions and head of the federal center attached to the president, replacing Sergey Shakhray. After Putin's appointment, the commission completed no such agreements, although during Shakhray's term as the head of the Commission 46 such agreements had been signed. Later, after becoming president, Putin cancelled all 46 agreements.
