Abbas has since confirmed that he turned down an Israeli offer for a Palestinian state on nearly 95% of the West Bank. In September 2008, Olmert had presented him with a map that delineated the borders of the proposed PA state, for which Israel would annex 6.3 percent of the West Bank and compensate the Palestinians with 5.8 percent (taken from pre-1967 Israel), which Abbas stated he rejected out of hand, insisting instead to demarcate the 4 June 1967 borders of Palestine. He said that Olmert did not give a map of the proposal and that he could not sign without seeing the proposal. Abbas also said that he was not an expert on maps and pointed to Olmert's corruption investigation (he was later convicted). Abbas said in October 2011 that he made a counteroffer to let Israel annex 1.9% of the West Bank.
