As I said earlier, in the interest of transparency and trust in the institution, the reason for nominations to the HoL (at the very least, those that pass vetting) should be a matter of public record.
It shouldn't just be a list of people that a PM/out-going PM just fancies giving an honour to. 
It's because there isn't transparency that there is a stench of nepotism/cronyism/bribery (delete as appropriate).
