European Competition Commissioner Neelie Kroes has hit back US senators who have publicly complained about Europe's ongoing examination of the Oracle Sun merger.

Kroes told US senators to mind their own business and concentrate on sorting out their own problems - starting with US healthcare.

Several high profile US senators including John Kerry signed an open letter to the European Commission last month which accused the regulator of dragging its feet over the $5.6bn deal in order to damage US business interests. US competition authorities have already approved the deal.

Speaking yesterday outgoing Competition supremo Kroes smacked US senators for: "interfering in someone else's decisions rather than taking the most important decision that you have control over: improving health care.", according to AP.

She told senators to get their priorities straight and concentrate on something they actually have control over.

Kroes is shortly to lose the Competition job to become "digital agenda commissioner". ®
