"It is extremely stupid because...[insert reasoning here]...?
Please avoid the logical fallacy of ad hominem just because you do not understand something that others do. Transparency and accountability in public services and in corporate governance is something that has taken decades to develop and is an essential part of an open democracy. I realise that this is of little interest to many people. But that does not make it extremely stupid. The fact that the current UK Prime Minister has a record of not declaring conflicts of interest is one reason speculation surrounds his decisions. For example, there has long been a claim he bought shares in Moderna vaccine whilst Chancellor of the Exchequer. Sunak has been slow to disclose his interests as he is supposed to do (claiming he 'inadvertently forgot'). Former PM's David Cameron and even the the ultra-shifty Boris Johnson were open about their register of financial interests, yet Sunak who boasted he would bring in 'accountability and integrity' has refused to reveal a large part of his interests, instead calling it a 'blind register'. So yes, the sudden change from the Fire Brigade just saying what vehicle caused a fire (model and make) to a generic 'accidental ignition', can only be Sunak protecting his likely financial interests (he owns Theleme which has a net value of £530m and is an investment company in the secretive Cayman Islands), so whilst Sunak might have 'stepped down' from running the company (i.e., 'blind') we have no idea whether his politics are centred around profiting from Jaguar Land Rover and the Tata deal, given his wife's associations and the fact of the Luton Airport Car Park fire said on the grapevine to have been a Land Rover, yet unlike Liverpool, it has not be confirmed. There is nothing illegal about Sunak's affairs*, however, the taxpayer has aright to transparency which is sovereign over any politician's personal affairs.
*Not to mention Infosys, in which Sunak had 50% shares which he handed over to his wife to take up politics, the multi-billion firm owned by Sunak's father-in-law Narayana Murthy, which has a registered company in Rwanda and Rwanda has...well, well, well...extensive lithium mines. Fancy that!
