The London Stock Exchange yesterday confirmed it was in detailed discussions with its German rival about an all-share merger. The exchanges have considered combining forces before. They agreed to merge in 2000 before a rival bid for the LSE from Sweden’s OM Gruppen scuppered the deal. The LSE then rejected a formal £1.3bn offer from Deutsche Börse in January 2005. So will it be third time lucky? Jasper Lawler, Market Analyst at CMC Markets, joins to discuss.
