Bishop Abel Muzorewa, who walked out talks with the white minority government claiming he had been insulted, announced yesterday that he would rejoin the discussions with Prime Minister Ian Smith.

A spokesman for the bishop's United African National Congress said Muzorewa had received an apology.

The announcement that the bishop would rejoin the talks followed a meeting between his aide, James Chikerema, and Deputy Prime Minister David Smith, who was identified by Muzorewa aides as the official who accused the bishop during the Friday meeting of telling lies. The meeting between Chikerema and Smith was unepected.

The government and the other two black delegations at the talks the Zimbabwe United Peoples Organization and the African National Congress delegation led by the Rev. Ndabaningi Sitholehad requested a private meeting of the delegation leaders.

A Muzorewa spokesman stated yesterday afternoon that "difficulties over the offensive language which led to the walkout . . . were satisfactorily resolved." But he stressed that there were still differences between the black leaders and the government over terms of the proposed internal settlement.

Muzorewa differs with the government over how the 28 white members of a new parliament are to be elected.

The government wants them elected by a separate white voters' roll.

Muorewa says he feels they should be elected by a common roll of all voters, both black and white, but says he is willing to compromise so that some of the white members would be elected by whites only.

The reconciliation yesterday follows an exchange of accusations between Sithole and Muzorewa.

Sithole accused Muzorewa of obstructing the talks and urged that they go on without the bishop.

Muzorewa denied press reports that he had left the talks to delay a settlement at the request of the British Foreign Office. He termed the reports a "load of rubbish."

Without mentioning Sithole by name, Muzorewa accused him of being an "Uncle Tom" for meeting with Smith after Muzorewa's walkout.

In a related development, a copy of the draft agreement the delegates were considering when talks broke down last week was leaked to the press.

It contained no surprises, calling for a new parliament of 72 blacks, and 28 whites, a bill of rights to guarantee individual liberties, private property and parment of pensions outside the country, and the freedom from political interference of the judiciary, the armed forces, the civil service and the police.

It also contained an agenda for the interim government, which included discussions on what will happen to the present armed forces, the release of political detainees, removal of discriminatory laws, and "creation of a climated" for democratic elections.
