Pots and kettles

So David Davis has warned the EU not to put politics before prosperity.

That would be the David Davis who supported the British Government when it decided to call an EU referendum for domestic political reasons (mainly to dish UKIP), utterly heedless of its leaders' (Cameron and Osborne) stated opinion that it would severely damage the UK economy.

That would be the David Davis who is part of the British Government which, for political reasons,  has yet to clarify what kind of post-Brexit deal it wants and whose leaders (May, Johnson, Gove, Fox, Hammond, etc) are far more concerned about their place in the future of the Conservative Party than the future economic health of the country.

That would be the David Davis who is part of the British Government which has consistently ignored the warnings of business organisations and trades unions about the severe economic consequences of the absence of an early settlement on transitional arrangements for Brexit.  Because to do otherwise would cause political turmoil on Tory backbenches.
