Earlier quoted context omitted.
The British PM isn't "basically" or in any way the head of state or of the legislature. The monarch and the House of Lords still exist and the latter should and very much do assert their power.
You believe that the monarch has any vestigial power?? If the PM calls the King to prorogue Parliament, they HAVE to do it. And the House of Lords has given its authority to the House of Commons. A British Prime Minister has more power than an American President.
I believe they are the head of state and that they carry out the functions of the head of state in a way that is consistent with comparable states such as Ireland or The Netherlands.
> And the House of Lords has given its authority to the House of Commons.
No they have not. The 1911 Act is alive and well. It is occasionally called into question but the Lords have retained their authority. And all of this is to say nothing of the courts etc.
> A British Prime Minister has more power than an American President.
This is neither here nor there in regards to the claim made above. They are not "basically" the legislature...
