House of Lords keeps government accountable by scrutinising legislation.
Far fewer hereditary peers after Blair's era, more life peers. These members have expertise in a certain area and are there because they are experts in their fields.
Independent from government and will delay proposals, even if popular with Commons (eg Social Care Bill 2012).
Lord's have to adhere to Salisbury Convention (they cannot block/delay bills that were in party manifesto).
Lords have more time and expertise to scrutinise legislation.
House of Lords is UNDEMOCRATIC
Lords are unelected; never face relection; are appointed by PM; very limited accountability.
Even though they are not elected, they get to second read the bills passed by Parliament.
Often elite members of society - not representative of the majority of the population.
Costs are substantial as Lord's can claim expenses and allowances, yet remain unelected by the people.
