Euronext, the pan-European exchange, is to transfer trading of all Dutch derivatives to its Liffe Connect platform next week, several months after it originally intended to complete the operation.

Once all markets are operating through the single platform, Euronext will spend €13.9m rationalising its IT operations. As a result, it will cut 80 jobs in London, of which 40 will be external contractors. This will reduce the exchange's 500-strong in-house workforce by 8%.
