The trading software provider Fidessa has pushed back a shareholder vote to approve a £1.3bn takeover bid from a Swiss rival, as it waits to see if higher counteroffers will be made.

Fidessa said on Friday that an April 5 meeting to vote on the Temenos offer would now take place on April 27. The decision was taken to allow the group to explore potential rival bids from ION Investment Group and SS&C Technologies.
