Answer:
The House of Lords, now constituted by a large number of prestigious intellectuals and businessmen from the United Kingdom, acts as an advisory body, on complex issues, for the United Kingdom. It is, in a nutshell, the "conglomeration of wise men of the United Kingdom". In this sense we can find deans of universities, renowned scientists, millionaires of age chosen for their contributions to the progress of the United Kingdom and the world, etc. A historical example that concentrates all these attributes is Lord Kelvin.
After the entry into operation on October 1, 2009 of the new Supreme Court of the United Kingdom, this body assumed the judicial function that until then held the Upper House through the Appellate Committee.
The House of Lords also has the role of controlling the government's performance through questions and investigation commissions. But this control is secondary, as it does not have the capacity to compromise the responsibility of the government. Although in recent history it was this Chamber that ended Margaret Thatcher's term when she began to exhibit unstable and tyrannical behavior on members of her cabinet and therefore on members of the House of Commons.
Thirdly, the House of Lords performs a legislative role. It has the ability to discuss the bills, and it does so in a freer, deeper, more flexible and more rigorous way than the House of Commons. It also reviews the legislative pieces that are sent to it from the House of Commons due to its technical complexity for deep analysis. And finally, the legislative function allows the House of Lords to reject laws submitted by the Commons, although only for a maximum period of one year.
