The Queen certainly does have power, including the power to sign international treaties and deploy British troops abroad. It's true that most of these "royal prerogative powers" are today exercised by government, but that in itself is a serious problem. These powers have been transferred directly from the monarch to the prime minister and don't need the approval of parliament, effectively shutting out the British people from important decisions. That is fundamentally anti-democratic – and it can only happen because we have a monarchy.
It isn't a problem at all.
Constitutionally speaking, the Queen is the government. However, the powers conferred on the Crown are 99.9% derived from Parliamentary legislation. The remainder are exercised by the Queen on the advice of her ministers. Pretty much the only exception is when the monarch has to decide who to appoint PM.
If the Queen decided to ignore ministerial advice, it would be no problem sidelining her. This has pretty much been the case since 1688.
The Queen and Prince Charles also have the power to veto bills that affect their private interests.
No.
The Queen has the power to veto bills, but that power has not been exercised in the UK for centuries.
Prince Charles has no such power at all. The power to veto only vests in the monarch.
Official legal advice makes clear that Queen's and Prince's Consent (as the "royal veto" is officially known) is not a mere formality. The process by which consent is obtained provides a clear opportunity for the Queen and the Prince of Wales to influence the shape and content of a bill before it reaches Parliament.
This is all crap.
If a government decides to give Charley Boy a quick squizz at a bill before it is introduced to Parliament, that's purely their decision. There is no legal obligation to do so. They can show it to anyone they like.
Then there's the problem of parliamentary sovereignty. At one point all the power in the land was held by the king or queen. Over time that power moved to parliament and is now held collectively by 650 MPs. However, the fundamental nature of that power hasn't changed – parliament can make or scrap any law it likes, just as the monarch could in the past. This means our freedoms are never really guaranteed because parliament can always decide to remove them. Again, this a direct result of having a monarchy.
I'm afraid this is so wrong that I hardly know where to begin. The supreme law making power in the UK is Parliament. The parliamentary chamber with all the power is the Commons, which is democratically elected.
The last time that any monarch in England had autocratic power was probably the thirteenth century, although perhaps rather later in Scotland.
Yes it is true that Parliament can choose to change any law it likes. That's a good thing. The alternative is having laws that the democratically-elected supreme law-making body can't change. A simple example of this is the right to bear arms in the US, or to put it another way, enslavement to the ideas of dead white men.
