" ..it must make sense to try & sign up the minister's man, who in the end is the one person who can ensure that you will be awarded the contract.
The system seems to work well, & as long as a minister deals only with reputable international firms & doesn't become too greedy, no one complains.
Fail to observe either of those two golden rules & the whole house of cards collapses. "
