The Peres/Abu Ala plan that was publicized yesterday may contain more than meets the eye. Transportation Minister Ephraim Sneh (Labor Party) told Israel Radio this morning that Abu Ala - named by Arafat as his future successor as PA head - said that the plan contains a side letter setting the future borders of a PLO state at the 1967 lines. The body of the plan, entitled “A Palestinian State First” and submitted yesterday by Foreign Minister Peres to fellow Labor Party MKs, calls only for the immediate establishment of a PLO state in areas now under PA control - 42% of Judea, Samaria, and Gaza. Abu Ala told Sneh that without the side letter, the Palestinians would not support the plan. Dr. Aaron Lerner of Independent Media Review and Analysis (IMRA) notes that Foreign Minister Peres has a history of writing secret side letters. In 1993, for instance, Peres wrote to then-Foreign Minister of Norway Jorgen Holst that he encourages the functioning of PA institutions in eastern Jerusalem - yet denied, for a while afterwards, that he had written it.
