In 1919, during the [[Paris Peace Conference, 1919|Paris Peace Conference]], British Prime Minister [[David Lloyd George]] repeatedly brought up the idea of a Channel tunnel as a way of reassuring France about British willingness to defend against another German attack. The French did not take the idea seriously and nothing came of Lloyd George's proposal.<ref>MacMillan, Margaret. "Paris 1919". Random House, 2002, p. 174, 194</ref>
 
In 1929 there was another proposal for the building a channel tunnel, but nothing came of this discussion and the idea was shelved. Proponents estimated construction to be about US$150 million. The engineers addressed the concerns of both nations' military leaders by designing two [[sumpssump]]—ones—one near the coast of each country—that could be flooded at will to block the tunnel. This design feature did not override the concerns of both nations' military leaders, and other concerns for hordes of undesirable tourists who would disrupt English habits of living.<ref>[http://books.google.com/books?id=wN4DAAAAMBAJ&pg=PA767&dq=Popular+Science+1930+plane+%22Popular+Mechanics%22&hl=en&ei=fxBvTp7pAoyhtwfhqq33CQ&sa=X&oi=book_result&ct=result&resnum=8&ved=0CEQQ6AEwBzgU#v=onepage&q&f=true "New Plan for Channel Tunnel" ''Popular Mechanics'', May 1929, pp. 767-768]</ref>
 
In 1955, defence arguments were accepted to be irrelevant because of the dominance of air power; thus, both the British and French governments supported technical and geological surveys. A detailed geological survey was carried out in 1964–65.<ref name="halcrow-film-1964-65">{{Cite web|title=Channel Tunnel Site Investigation - 1964 - Halcrow Group|publisher=Halcrow Group|date=13 July 2011|url=http://www.halcrow.com/Who-we-are/film_archive/Channel-Tunnel-site-investigation-film/|accessdate=26 July 2011}} Online presentation of a 1964–65 film documentary of a geological survey of the Channel, with a brief summary.</ref> Construction work commenced on both sides of the Channel in 1974, a government-funded project using twin tunnels on either side of a service tunnel, with capability for car shuttle wagons. In January 1975, to the dismay of the French partners, the British government cancelled the project. The government had changed to the [[Labour Party (UK)|Labour Party]] and there was uncertainty about [[European Economic Community|EEC]] membership, cost estimates had ballooned to 200% and the national economy was troubled. By this time the British tunnel boring machine was ready and the Ministry of Transport was able to do a {{convert|300|m|abbr=on}} experimental drive.<ref name="Wilson pp. 14–21" /> This short tunnel would however be reused as the starting and access point for tunnelling operations from the British side.
