The UK government on Thursday introduces legislation to axe seats in the House of Lords retained for hereditary lawmakers as it moves to reform parliament’s unelected upper chamber.

The bill will remove the 92 seats reserved for peers who inherited their position as a member of an aristocratic family.

They hold titles such as duke, earl, viscount and baron. Britain is an anomaly among western governments in having such lawmakers.

The move was a manifesto commitment of Prime Minister Keir Starmer’s Labour party ahead of its landslide general election win in July, which returned it to power for the first time in 14 years.

It resurrects reform of the Lords that started under Tony Blair’s Labour government in the late 1990s.

“This is a landmark reform to our constitution,” constitution minister Nick Thomas-Symonds said in a statement.

“The hereditary principle in law-making has lasted for too long and is out of step with modern Britain.

“The second chamber plays a vital role in our constitution and people should not be voting on our laws in parliament by an accident of birth,” he added.

The legislation will easily pass the House of Commons lower chamber due to Labour’s massive majority before it will have to be approved by the Lords.
