Jon Moynihan

Moynihan was the Chairman of the Liz Truss leadership campaign in 2022, which led to her becoming prime minister in September 2022.

This omission was said to be one of the causes of the failure of Truss's and Kwarteng's budget on 23 September 2022, which attempted to rip up decades of treasury orthodoxy. In an influential commentary Moynihan evidenced that the prime cause of market disruption at the time was the Bank of England's bungling.

In 2021, Moynihan was named as one of UK's "Top 75 Catholic leaders".

In June 2019, he donated £100,000 to Boris Johnson during the 2019 Conservative Party leadership election.

Moynihan supports Brexit. Prior to the 2016 referendum, he was a member of the eurosceptic campaign group Business for Britain and sat on its board. While at Business for Britain, he was chairman of the editorial board, and came up with the name for Business for Britain's influential 1,000+ page argument for Brexit, "Change, or Go". He was the chairman first, of the campaign committee; then of the finance committee, and a member of the board of the official pro-Brexit campaign organisation, Vote Leave and was their final Chairman. Moynihan is the chairman of the pro-Brexit right-wing think tank Initiative for Free Trade.

From 1995 on, he founded, chaired and brought to success numerous startup companies. As a journalist/author, Moynihan has been published extensively on topics such as trade, economics, health and football.

He co-founded, with Helen Bamber OBE, and was the founding chairman, of the Helen Bamber Foundation. He created a proposal for the Brompton and Marsden Hospitals to merge with other health organisations on the Chelsea Medical campus site.

At the company, he transitioned the ownership of the firm from a trust to an employee-owned model. Moynihan wrote a charter of ethics that was mandatory for employees to sign up to. He was credited for turning around the company in the 1990s. Moynihan retired at the end of 2013 as chairman, having run PA for some 22 years, but remained as Chairman and a principal of its venture capital arm, Ipex Capital. In 2015, American private equity firm The Carlyle Group obtained a 51% share in the company, valuing PA at $1 Billion. In 2020, PA was re-sold to Jacob's Engineering at a value of $2.5 Billion.
