Can I ask what's possibly a dumb question? Isn't there a further problem, namely that once one steps into political lobbying that should be the end of one's charitable status? (That's why Amnesty has never been a registered charity).
I believe thats where the Conservatives would like this to go ultimately. They have the numbers to force this through if they decided to go that way at present. We shall see if it is something that they attempt to do (It might be harder than you think because of the sheer power and influence of the charity sector).
The problem comes in how you define political lobbying. It can severely restrict how a charity can operate.
There is a clause in the Transparency of Lobbying, Non-Party Campaigning and Trade Union Administration Act 2014, which has been particularly problematic as it relates to activity during an election campaign period.
During the 2017 election, due to the lack of clarification over what the act meant in practice, there were concerns it was stopping charities from being able to operate as they should:

‘Unreasonable’ legislation preventing campaigns on issues affecting poorest and most marginalised in society, states open letter signed by more than 50 charities
It depends on the nature of your charity, but it seemed to be particularly problematic for charities dealing with refugees and food banks. Though there are some name in there which might make you raise your eyebrows too.
New guidance on the Act was issued in 2018 and then in 2019, which was supposed to clarify the problem and resolve some of the issues.

However I think it still remains a bone of contention that is split along party political lines. See my post above about this.
The danger is that the Act could be used to stop criticism of the sitting government during an election campaign which limits its public accountability.
I personally think it might be better to have some obligation to have some sort of political declaration in the aims of a charity and how much is directly spent in this area with it being separated out from 'charitiable spending' in accounting.
This way its more transparent without it tipping the balance in favour of the state and big business.
