There are currently 181 (at 2013) crossbench members in the House of Lords. They are
members who have no party-political affiliation and participate in parliamentary proceedings independently. They do not adopt collective policy decisions, but rather speak and vote
as individuals. For administrative purposes all crossbenchers are part of the crossbench group. The group elects a Convenor whose role it is to provide information to crossbenchers
and represent their interests in the House.
