They include 70 homicides and more than 550 sexual offences.

Official papers unearthed by the National Archives reveal the prime minister's frustration and concern over slow progress securing supplies of what was then seen to be a brand new "wonder drug".The BBC was shown the papers ahead of the anniversary of the Normandy landings on 6 June 1944.

Even months after D-Day, the wartime prime minister called efforts "very disappointing" and bemoaned the fact the US was "so far ahead" despite the drug being a "British discovery".Penicillin was discovered in London by Professor Alexander Fleming in 1928. Despite attempts to produce a usable medicine from the bacteria-killing mould, this had not been achieved by the start of World War Two.But an Oxford team of scientists, led by Howard Florey, carried out the first successful trials. With large-scale production difficult in the UK, they took their research to the United States, where drug companies expanded output.

Before the development of penicillin, blood poisoning could follow even minor wounds with no cure available. So with the anticipation of the huge military effort ahead, supplies of the drug were seen as essential.Early in 1944, the prime minister was complaining to his ministers about Britain's inability to produce it at scale. He scrawled in red ink on a Ministry of Supply report that said the Americans were producing greater quantities: "I am sorry we can't produce more".

Later in the year, in response to explanations from officials, he said: "Your report on penicillin showing that we are only to get about one-tenth of the expected output this year, is very disappointing."

On another report, he instructs: "Let me have proposals for a more abundant supply from Great Britain".The turning-point was, she argues, also triggered by Denmark's neighbour, Germany, allowing a million refugees and others to stay in the country, during the migrant crisis.

"That was a political choice that had repercussions across Europe."By 2015 the anti-migration Danish People's Party was the second biggest power in Denmark's parliament. But at the same time, the Social Democrats - under new leader Mette Frederiksen – decided to fight back, making a clear, public break with the party's past reputation of openness to migration.

"My party should have listened," Frederiksen said.Under her leadership, the party tacked towards what's generally seen as the political "far right" in terms of migration and made hardline DPP-associated asylum policies, their own. But they also doubled down on issues more traditionally associated with the left: public services.
