They're losing £100m year on year which is being covered by the parent company in Dubai. I guess DP World have said enough is enough and are looking to restructure the business to reduce cost, or they'll just wind it up.
Now whether the Government see this a strategic transport link and buys it off the Holding Company remains to be seen.
The only problem with "Nationised" Companies is they go on strike at a drop of a hat ( see TfL ) and lose even more money.
The huge advantage with Nationalised Companies is that any profits will benefit US ALL as profits are not creamed off just for shareholders.
Nationalised Companies are also subject to public /political control/pressure - see eg EDF, the French Nationalised Energy Company which is capping energy rises at around 4%. I think most people here would be pleased with that! The irony is that EDF's profits here go back to France to benefit the French instead of us. If our Energy Companies were nationalised they'd stay here.
Workers in most industries are allowed to go on strike. They only strike ( losing money) when they are pretty desperate. Workers who aren't allowed to go on strike (except certain defined areas) are called 'slaves' I believe. We supposedly abolished slavery a long time ago.
