According to recent reports, 47% of UK workers are looking to side-hustle to cope with the cost of living. But new data suggests the best way to find lucrative secondary income might be running for office.

Moneyzine.co.uk can reveal official earnings figures from UK MPs’ ‘side hustles’ - and they cast considerable light on the incentives driving today’s political elite.

Conservative MPs top earnings list

Debates over politicians’ financial incentives are nothing new. But with a looming recession - these questions may be about to come back to the fore.

A clear trend has emerged from this data: Tory MPs are by far the highest earning ‘side hustlers’, with 8 of the top 10 MPs serving as Conservatives. Of the top 25 who collectively earnt 15 million since 2019, 16 are Conservative - joined by 7 Labour MPs and 2 Lib Dems.

Part of this may be explained by the ‘PM premium’. The experience of occupying No. 10 appears to translate into earning power - each of the (many) PMs the UK has had since 2019 feature in the top 10 earners. Equally, Conservative MPs may be more likely to be involved in private businesses or come from high-powered backgrounds which facilitate future earning - such as Rishi Sunak’s well-publicised background as a partner at two Hedge Funds.

Method matters

Much of the backlash against these figures will be generalised anger. But it’s worth considering the specific means through which MPs earn.

Boris Johnson’s £1.2 million was earned primarily through speeches; one report suggests this worked out at roughly £31,000 per hour. Similarly, Theresa May’s earnings were buffered by a speech given in Saudi Arabia - a country she had previously criticised amidst the murder of a journalist during her tenure as Prime Minister. This may be seen as hypocritical, especially given the six-figure payment she received for the talk.

While there is obviously no question about the legality of these earnings, it might be argued that insufficient media attention to potential conflicts of interest - which leads to a permissive atmosphere and perpetuates the cycle.

These figures really put the current economic crisis into perspective. There’s nothing wrong with earning, but this data should prompt tougher questions about whether MPs’ apparent dedication to public service is compatible with such vast private gains.
