  • Part of the £130m network with Marshall, Legatum, Harborne

Research Notes

Key questions:

  • Total donations: What's the complete donation history to all parties/causes? Need full Electoral Commission search.
  • Fossil fuel holdings: Full list of fossil fuel companies Marathon owns shares in?
  • Anti-net-zero funding: Which specific campaigns/organisations has he funded?
  • Jersey structure: What's the exact ownership structure via MAM Investments?
  • Network overlap: Full overlap with other £130m network members (Marshall, Legatum, Harborne)?
  • Companies House: Full directorships, PSC records for all his companies

Leads to follow:

  • Electoral Commission complete search: "Jeremy Hosking", "Marathon Asset Management"
  • Companies House: Marathon Asset Management, Hosking Partners, MAM Investments
  • DeSmog investigation: full fossil fuel holdings (£1.8bn+ shares)
  • openDemocracy: anti-net-zero campaign funding details
  • Cross-reference with other £130m network donors

Red flags:

  • £2.4m+ to Reform UK from offshore-linked wealth
  • £1.8bn in fossil fuel investments while funding anti-climate campaigns
  • Jersey-registered parent company raises transparency questions
  • Part of coordinated £130m network with other billionaire donors
  • Funding both electoral politics AND issue campaigns (multi-vector influence)

Significance: Hosking represents the fossil fuel → right-wing politics pipeline:

  1. Fossil fuel wealth funding populist right parties
  2. Offshore structures obscuring transparency
  3. Anti-climate campaigns protecting investment interests
  4. Coordinated network with other billionaire donors
  5. Multi-vector influence (electoral + issue campaigns)
