Former Trade Minister Phil Goff believes Prime Minister John Key has invented a suggestion that Labour also considered a "commercial solution" to settle a dispute with a Saudi Arabian investor which was damaging relations with New Zealand.
Mr Key has hinted that Cabinet papers would emerge soon to embarrass Labour over its criticisms of National's commercial solution to settle the dispute with Hamood Al Ali Khalaf about the ban on live sheep exports from New Zealand.
Labour has received 10 Cabinet papers from its last term in Government relating to live sheep exports with Saudi Arabia - as it is entitled to receive so long as it keeps them confidential.
But Mr Goff says there is nothing in the papers to embarrass Labour nor is there any reference to a "commercial solution" as Mr Key suggested.
"There is nothing in any of those papers that refer to that at all so either he has made it up or he is referring to some document that I don't know about," Mr Goff said.
