Sir, – Power is such an addiction.

Often individuals who have been granted power struggle with the responsibility and their mistakes are exposed.

I remember writing at the time of the MPs expenses scandal about the need for clarity in claims.

Political lobbying is a very different issue, but what lies at the heart is the ingredient that is associated with power and the privilege it brings – greed.

It is human nature to want more, but the reality for most people is that such a craving is restrained or restricted.

There is guidance on what we can and cant do.

At a time of waning support for politics and increasing suspicions as to what some of our elected representatives get up to, it raises a fundamental point about MPs and members of the House of Lords – what are they there to do, and what is strictly out of bounds for them?
