"Boris" has not sold Cobham because Cobham is not Boris's to sell! This is a perfectly normal M & A transaction, they happen all the time, and while it is true that the UK is THE most open market in this respect, (if this company was French or Italian then their Govt's would never have permitted the sale) there are a whole raft of UK acquisitions of similar US defence companies, in fact Cobham itself bought its US rival Sargent Fletcher some years ago. This is not some one sided sell off, it is normal commercial activity.
