The Johannesburg Stock Exchange is in talks about switching to the London Stock Exchange’s MillenniumIT trading platform. The deal would help to cement the existing relationship between the two exchanges and be seen as a boost to the LSE's efforts at creating a global technology franchise.

Under the deal, the JSE would move from its present equities trading system, also provided by the LSE, onto MillenniumIT, the Sri Lankan platform that was acquired by the LSE in December 2009, according to a source familiar with the situation. Talks are understood to be at an advanced stage. The JSE's present contract with the LSE expires in 2012.
