Finance Minister Francois Baroin joined a chorus of French criticism of the British economy on Friday, exposing strained relations with London as concern grows that France's credit rating might be cut.

The economic situation in Britain today is very worrying, and you'd rather be French than British in economic terms, Baroin told Europe 1 radio.

Relations between Paris and London have become increasingly frustrated since Prime Minister David Cameron refused to sign up a week ago to a European summit deal on the region's debt crisis.

Bank of France chief Christian Noyer attacked credit ratings agencies this week, saying that if they considered economic fundamentals they should downgrade Britain - which had as much debt, more inflation, less growth than us - before France.

Standard & Poor's is reviewing France's top-notch AAA rating for a possible downgrade, as part of a wider review of euro zone ratings following the summit deal.

It's true that we have no lessons to give, but we don't have to receive any (from Britain) either, Baroin added.

Jean-Pierre Jouyet, head of France's AMF markets regulator said this week that Britain's political right was the world's stupidest, as it served purely financial interests and not the national interest.

France and Britain clashed at the summit, when Cameron vetoed a revision to the European treaty, forcing other member states to seek other procedures to tackle the crisis.
