The row is likely to - and is no doubt meant to - damage Mr Hammond's chances of becoming Prime Minister if Theresa May stands down later this year.
"It appears that Cabinet members haven't yet finished negotiating with each other, never mind the European Union", he said. The trade secretary said in a Bloomberg TV interview Thursday he would be "very happy" with a transition period of just "a few months".
Mr Hammond did not give such an explicit denial to the claim in the Sunday Times that he had branded public sector workers "overpaid".

A Cabinet minister failed today to paper over glaring Cabinet rifts on Brexit and public sector pay. "Two-thirds believe cuts to public services have gone too far and three quarters want to see a pay rise for public sector workers this year".
Speaking on the BBC's Sunday Politics show, International Trade Secretary Liam Fox said any transitional period should be "very time-limited", and should allow the United Kingdom to strike new trade deals - something it is unable to do as part of the EU's customs union.
