In short: Ernest Marples was a controversial Conservative politician who oversaw the expansion of the UK motorway network while maintaining significant financial stakes in the construction industry. His career was marked by allegations of corruption, a secret life, and a dramatic flight to Monaco to escape a massive tax bill.

Born in Manchester in 1907, Ernest Marples rose from humble beginnings to become a key figure in the Conservative governments of the 1950s and 1960s. As Postmaster General, he introduced the Premium Bond scheme and early postcodes. However, his tenure as Minister of Transport from 1959 to 1964 remains his most contentious legacy. During this period, he oversaw the Beeching cuts, which dismantled a significant portion of the national railway network, while simultaneously championing major road projects like the M1 motorway.

Marples' political career was plagued by persistent conflicts of interest. Before entering the cabinet, he co-founded the civil engineering firm Marples Ridgway and Partners. Despite resigning as managing director upon becoming a junior minister in 1951, he retained 80% of the company's shares. When he became Minister of Transport in 1959, he was required to divest, yet he struggled to do so. His attempts to transfer shares to his wife were blocked by the Attorney-General, Reginald Manningham-Buller, who suspected a scheme to buy them back later. Meanwhile, his firm secured lucrative government contracts, including the Hammersmith Flyover.

Beyond his professional controversies, Marples lived a complex private life. A 1963 investigation by Lord Denning confirmed rumours of his private habits, which were later corroborated by diaries revealing a fetish for being whipped while dressed in women's clothing. By the mid-1970s, Marples faced mounting legal and financial pressure, including lawsuits from tenants and banks, as well as demands from the Inland Revenue for decades of unpaid taxes. In 1975, he fled to Monaco to avoid prosecution, leaving behind a life of luxury in Belgravia. He died in 1978, leaving a legacy that continues to spark debate, even serving as the namesake for a 2009 campaign to open UK postcode data.
