Thank you very much.
I have to say that's not an easy question. I think it's an interesting question from a lobbying perspective, because obviously, lobbying is not defined as corruption, but rather, it's defined as influence that needs to be regulated through transparency.
The easiest approach to corruption and arguably the easiest to define in various OECD member systems is simply the payment to a public servant or a public official to advance a private interest. It means making a financial payment to influence a public servant's decision or doing that person a favour, to advance a private interest at the expense of the public interest and to alter the decision that the official ought to have made in the public interest.
That's the most common definition and the broadest one. When it's applied to more specific contexts, such as public procurement or securing licences or licensing agreements, it consists in paying a public servant to secure a licence that would otherwise not have been granted.
That's one of the most common examples.
