President Boris Yeltsin returned unexpectedly to the Kremlin yesterday for the first time this year, just two days after being discharged from hospital. Mr Yeltsin, who was 68 on Monday, returned to his Kremlin office to meet his chief-of-staff, Mr Nikolai Bordyuzha. His first decision was to recommend that Russia's upper chamber of parliament approve the resignation of prosecutor general Mr Yury Skuratov, who last year accused the central bank of pilfering more than $1 billion. Mr Yeltsin spent a quiet day on Monday marking his birth day at the Barvikha sanatorium outside Moscow.
