A two-week crisis for Rhodesia's biracial interim government ended yesterday with a decision by Bishop Abel Muzorewa's party that it would not withdraw from the government's Executive Council.

The decision means that Muzorewa and his United African National Council have lost by default their first standoff against the three other members of the transitional government, correspondent Caryle Murphy reported. Muzorewa's group is thought to have the support - as yet untested - of most of Rhodesia's 6.7 million blacks.

The party's leaders had been weighing whether to withdraw from the government to protest the dismissal of Justice Minister Byron Hove two weeks ago.

Muzorewa's party did decide, however, that the bishop would not join the other three leaders of the government at any future political rallies. Other members of the government ruling council are Ian Smith, leader of the former white minority government, and black leaders Ndabaningi Sithole and Jeremiah Chirau.

It was still unknown whether Muzorewa can sell his party's decision to his grassroots supporters. Observers here say he already has lost some support, failing recently to draw the large numbers of supporters to rallies that he did in the past.
