Travelport has become the ninth company in as many working days to withdraw an initial public offering from the market, continuing a jittery start to the month in which companies have had to rely on deep discounts to push through deals.

Books were set to close on the Travelport float, which aimed to raise close to $2bn (€1.5bn) and would have been the biggest initial public offering in London for two years, on Thursday. The travel company is owned by a group of investors that includes private equity firm Blackstone. Credit Suisse, Deutsche Bank, UBS, Barclays and Citigroup acted as Travelport's joint bookrunners.
