Was Philip de Laszlo a secret agent and was MI5's source really as they claimed? Did an enemy spy really paint the portrait of the young Princess Elizabeth? In 1917, noted society portrait painter Philip de Laszlo, who painted such luminaries as the Pope, the Austrian emperor, King Edward VII and Prince Louis Battenberg, was subjected to a secret tribunal which interned him for trading with the enemy. At the outbreak of the First World War, de Laszlo had pulled strings to be naturalised as British, but in 1919 he was referred to a public committee to revoke his naturalisation. With the aid of skilled counsel, de Laszlo had the application overturned - however, newly discovered records show MI5 had evidence obtained from a top-secret source that alleged that he was supplying the enemy with important information on politics and industrial production. Crucially, the source's anonymity prevented MI5 from presenting evidence to the tribunal, which has particular resonance in the contemporary War on Terror. In the only book to examine MI5's secret evidence, Phil Tomaselli explores these allegations and reaches a shocking conclusion.

The Second World War was the defining conflict of the twentieth century and it is one of the most popular and fascinating areas for historical research - and for family historians. More records than ever are available to researchers whose relatives served during the war. And this new book by Phil Tomaselli is the perfect guide to how to locate and understand these sources - and get the most out of them. He explains how, and from where, service records can be obtained, using real examples showing what they look like and how to interpret them. He also examines records of the military units relatives might have served in so their careers can be followed in graphic detail. The three armed services are covered, along with the merchant navy, the Home Guard, civilian services, prisoners of war, gallantry and campaign medals, casualties, women's services and obscure wartime organizations. Also included are a glossary of service acronyms, information on useful websites, an introduction to the National Archives and details of other useful sources.
