If this is true (and I know nothing) it is typical of all big company management. If your predecessor diversified, cut back to the 'core business' and blame the year one losses on him. The inverse will also apply. If he decentralised, centralise, or vice versa. Blame as above.
It will take about four more years for your plan not to work. You will then collect your five million quid and leave, and your successor will start all over again.
A classic example was Ford, a fairly well run company, that bought Kwik-Fit for UKP1 billion and sold it a few years later for about UKP 300 million. They must have been wrong, either to have bought it in the first place or to have sold it. It's the kind of short term thinking than bugs business in the UK and America.
