British negotiator Ivor Richard today emerged apparently ruffled and angry after a long meeting with Prime Minister Ian Smith to break the deadlock in the Geneva conference on Rhodesia.

"We had a vigorous exchange and as a result I now understand his position better and he understands mine," said Richard, who then uncharacteristically pushed past waiting reporters without another word.

Richard spent nearly three hours with Smith who, in a New Year's Eve broadcast, described reported British proposals to break the impasse at the Geneva conference on Rhodesia's future as "unrealistic."

While the two men met at Independence House, Smith's white colonial-style official residence in a wooded Salisbury suburb, about 500 blacks protesting a government ban on demonstrations marched in the black township of Harari three miles from Salisbury's center with banners reading "We don't want an imposed leadership," and "Richard talks to Zimbabweans." Zimbabwe is the nationalist name for Rhodesia.

Meanwhile, a new political party, The People's Movement, owing allegiance to the militant nationalist leader Robert Mugabe, has been formed in Rhodesia.

Mugabe, who has been banned from Rhodesia, was head of the Zimbabwe African National Union (ZANU). ZANU was linked to Joshua Nkomo's faction in Geneva under the title, The Patriotic Front.
