Which indirect taxes could fund higher public spending?

Can you give a possible working plan for financing the spending, rather than generalising about borrowing and indirect taxation?

No costed plan is offered, only examples of possible indirect levies and an explicit limitation of fiscal expertise.

Asked for a working plan, Alex Clarke explicitly says public-finance design is outside his speciality. The examples offered include levies on sugar, alcohol and vehicles, which can be presented through health or environmental aims while also raising revenue. Charges on goods affect household costs even when headline income-tax rates remain unchanged. Existing trade agreements are given as a reason direct British tariffs would be less straightforward. Charges at the point of sale are compared with import charges, alongside a brief interpretation of American tariff policy. These are possible mechanisms and the recording's interpretations, without a calculation demonstrating that they would fund the promised spending.
