Liberal Democrat peers used to be in a remarkably privileged position in the party. Not only because they have held office without the pesky need for elections but also because for many years the third party in the House of Lords has been the key swing vote when the government has been wanting to get legislation through.
That has meant many peers were well used to having direct access to ministers, and moreover being in a strong position to extract some concessions. As a result, many peers can point to numerous changes they have achieved to legislation.
