On 6 November, the ECB published a letter written by Jean Claude Trichet in his former capacity as ECB president, to Brian Lenihan. The letter, dated 15 October 2010, referred to the provision of liquidity from the Eurosystem to Irish banks. It also contained a warning that such provision of liquidity should not be taken for granted.  It was highlighted that the four year economic strategy of the Irish Government would be assessed by the ECB.
