ABP, whose 21 ports handle about 25% of British seaborne trade, including a large proportion of timber and forest product imports, is now owned by Admiral Acquisitions UK Ltd, which is run by investment companies led by Goldman Sachs.

The August 14 sale completion ends a protracted takeover battle in which Admiral Acquisitions twice raised its bid to see off a late challenge from fellow investor the Macquarie consortium. ABP shareholders voted in favour of the deal in July.

Five directors have now resigned from the board of ABP Holdings Ltd.
