If you find information that political parties are not allowed to receive donations from trade unions, workers’ organisations etc, code “YES”. Also code “YES” if it is stated that such entities are banned from giving support, contributions or donations to political parties. Also code “YES” if legislation includes an exhaustive list of allowed sources of income for political parties, and this does not include any of the above. By an “exhaustive list” is meant where it is stated something like “political parties are only allowed to receive income from the following sources” or (more vague) “parties may receive funding from the following sources”. If it says something like “allowed sources for political parties include...” it is not exhaustive. If you find information about allowed or banned sources for political parties and there is no mention about the sources mentioned above, code “NO”. Note that if you find information that trade union funding is banned from being used in election campaigns, but it is not explicitly stated or clear from the context that it relates specifically to political parties or candidates, code “NO” for both this and the following question. If you have not found any information and you judge that there may likely be regulations you have not been able to access about this issue, code “ND”.
