Before accepting the invitation, you can call us to find out what we think. We are objective and we have an overview, which the MP doesn't necessarily have. We give advice on these issues, but people don't have to follow it. For example, we can tell MPs that we strongly recommend that they not accept invitations like that. If an MP decides to go anyway and someone complains, we will find out. That's why we need to be consulted.
Some of your friends or family members may have an interest in you that isn't friendly or familial, which is why they offer you certain things.
