Dizzy makes a splendidly straightforward suggestion, why don’t politicians have one bank account for donations? They then record each transaction’s source on a register. Guido would also suggest that benefits-in-kind went on the same register. Both the account and register records would be made publicly available online.

If a politician failed to report an item within 30 days they would get a fixed fine of £100. If they failed to report an item after 60 days a £1,000 fine. If they fail to report an item after 90 days a mandatory one month suspension from the house – unpaid.

Party and constituency reporting would continue as now. To accept donations any other way would be a criminal offence. Simple enough even for the most incompetent politician…
