Boris Johnson has been "behaving strangely" since he published his personal blueprint for Brexit and is clearly "out of the loop" in relation to withdrawal negotiations, Ireland's European Union commissioner has said.
Agriculture commissioner Phil Hogan said the British foreign secretary was obviously not involved in the exit talks with the European Union as he has made statements "completely at odds" with the government's own position.
Mr Hogan also said Mr Johnson appeared a "diminished figure" in the Cabinet, in a potential sign of the reaction in the EU to his explosive intervention on Brexit.
The commissioner told the Evening Standard: "Clearly, he is not directly involved in the negotiations on behalf of the British government with the EU.
"He certainly has made very strange statements that are completely contradictory, and completely at odds with his own government's position as well as the possibility of being reasonable with the EU in finalising a deal.
"So it strikes me that he is completely out of the loop in relation to the type of concrete proposals that are required and that are being considered by the UK government."
Mr Hogan went on: "Mr Johnson is behaving and acting and speaking strangely.
"It's clear that his reputation is not good and he is a diminished figure in the government."
The threat to Theresa May of Mr Johnson's potentially damaging resignation from the Cabinet appears to have receded with agreement reportedly reached on the thrust of the prime minister's crunch Brexit speech in Florence on Friday.
The foreign secretary has backed away from his previous insistence that the UK should cease payments to the EU after the date of Brexit in 2019, accepting that Britain should "pay our dues" during any transition period, as well as meeting financial demands "where our lawyers say we are on the hook for stuff".
Mr Johnson has sought to downplay the significance of his 4,000-word personal Brexit blueprint, which has overshadowed preparations for Mrs May's speech and sparked speculation that he might be preparing to walk out of the Cabinet.
Mr Hogan said: "It's amazing that the UK's foreign secretary can publish a 4,000-word article about the UK's Brexit future and not mention the Irish border.
"You'd think that the foreign secretary would have ideas about how to manage the UK's main land border with the European Union, but obviously not.
"So if Mrs May is as vague on the three questions as Mr Johnson was in her speech in Florence then the signs will not be good."
