This petition was rejected

The Government e-Petitions Team gave the following reason:

There is an independent process for considering nominations for awards and honours, and advising the Queen on granting these, so ithis is not something the Government or House of Commons are responsible for.

If you wish to give feedback on the House of Lords nomination process you could contact the House of Lords Appointment Commission:

You could start a new petition calling for the Government to restrict who can be made a peer, which include preventing family members of the current Prime Minister from being made peers, if that is what you want to happen.
