What are the rules on political donations and gifts in the UK?

In the UK, political donations and gifts are increasingly under scrutiny, especially from mega-donors and overseas investors. There's a heated debate about whether there should be stricter caps on donations to prevent powerful interests from swaying elections. While current rules allow voters to financially support their preferred politicians as long as they adhere to spending limits during elections, growing concerns about transparency and influence have sparked calls for more stringent regulations. This debate highlights the broader issue of maintaining fair and democratic electoral processes.
