Feb 1 (Reuters) - The following bids, mergers, acquisitions and disposals were reported by 2100 GMT on Thursday:
** Britain's Sainsbury's SBRY.L said it has purchased the Nectar loyalty card business from Canada's Aimia AIM.TO for 60 million pounds ($85 million), boosting the supermarket group's control of customer data. Danish telecoms operator TDC TDC.CO has agreed a $2.5 billion takeover of Swedish Modern Times Group's MTGb.ST broadcasting and entertainment business, the latest deal in a global wave of mergers reshaping the telecoms and media sectors. Melrose Industries MRON.L pressed the case for its 7.2 billion pound ($10.2 billion) hostile bid for British engineer GKN GKN.L , ruling out a "hasty separation" of GKN's automotive and aerospace if it won control. German builder Hochtief HOTG.DE is set to win unconditional EU antitrust approval for its bid to buy Spanish airports and motorway operator Abertis ABE.MC , a person familiar with the matter said. Singapore Medical Group Ltd SMGL.SI and South Korea's CHA Healthcare Co Ltd have together bought a majority stake in Australia's fourth-largest fertility clinic operator, City Fertility Centre. Canadian private equity firm Onex Corp ONEX.TO and Brookfield Asset Management BAMa.TO said they do not intend to make an offer for IWG plc IWG.L , sending shares of the British serviced office provider down more than 20 percent.
