MOSCOW (AP) _ A top aide to Boris Yeltsin on Sunday denied there is a serious rift between the Russian president and Prime Minister Yevgeny Primakov.

``Differences do occur,'' the deputy chief of the Kremlin staff, Oleg Sysuyev, said in a television interview. ``But there is no antagonism there whatsoever or plans to dump this government.''

Moscow has been filled with rumors Yeltsin planned to fire the prime minister or other top Cabinet officials ever since Primakov submitted a proposal two weeks ago calling for Yeltsin to relinquish some of his powers in return for peace with the opposition-dominated parliament.

Yeltsin said he had no intention of relinquishing any power.

Appearing on the Sunday evening television news magazine, ``Mirror,'' Sysuyev said talk of a falling-out had ``nothing to do with reality.''

In addition, he said, ``the rumors about possible resignations of a whole number of Cabinet members are spread by unscrupulous politicians.''
