LONDON, May 11 (Reuters) - Australian banker Lex Greensill on Tuesday said he would not have described former British Prime Minister David Cameron as his friend, and only met him a few times during a spell working as an adviser to the British government. “I wouldn’t say that Mr Cameron and I were friends,” Greensill told a parliamentary committee. “I met him a couple of times in the time that I worked with the Cabinet Office.” Cameron, who was prime minister from 2010 to 2016, went on to work for Greensill Capital, a supply chain finance company which collapsed earlier this year. Messages released earlier on Tuesday showed Cameron extensively lobbied senior ministers on Greensill’s behalf.
