Again, basic economics. It is illegal in the EU and UK to "confiscate" property that is legally owned without sufficient reason.
In short, your copy and paste response is nonsense. You can't just "nationalise'" things for free, or else the government would be sued heavily and for good reason.
This is the UK, not the Soviet Union.
Just because politicians arse lick big corporations doesn't mean governments are powerless. The government can tomorrow pass a law in parliament banning foreign ownership in football and the club owners can't do shit about it. Nationalization is recognized by international law aswell. Sufficient reason is that it is "public purpose". Check the following link and learn what powers governments have:
In May 2019, Labour announced its detailed plan to nationalise electricity and gas transmission and distribution companies. The plan, entitled “Bringing Energy Home”, provides that the nationalisation would be effected by an Act of Parliament with a two-step process: (i) the assets are transferred into public ownership; and (ii) provision is made for compensating the former owners through a bond issuance by the Treasury. Labour has previously stated that the compensation should relate to the book value of the companies, but in Bringing Energy Home, it explicitly stated that
the level of compensation should be decided by Parliament.
Article 1 of Protocol 1 to the ECHR (incorporated into English law under the Human Rights Act 1998), which affords individuals and companies the right to peaceful enjoyment of their possessions.
Under the Article, the UK would have the right to nationalise assets, but only insofar as this is “in the public interest and subject to the conditions provided for by law and by the general principles of international law”. While these principles give Member States a wide margin of appreciation as to what constitutes “in the public interest” so as to allow for nationalisation, these principles also provide a right to reasonable compensation for affected parties. Previous case law provides that:
• Compensation must be of an amount reasonably related to the value of the property.
•
Compensation does not necessarily entail the full market value of the property if the legitimate objective of the public interest justifies less than full reimbursement
• The valuation method for calculating compensation must be “manifestly reasonable”, although
in practice the European Court of Human Rights (“ECtHR”) has granted national authorities wide discretion in this area and will generally respect their approach unless it is “manifestly without reasonable foundation”
As far as UK not being Soviet Union is concerned, you should read up on pre & post war nationalisation of various industries by the british government through various acts of parliament where private businesses were taken over for a pittance in "public interest". Power of a government is the same everywhere whether it is the UK, Soviet Union or Timbuktu.
