Margaret Thatcher's 'ideological mentor' urged her to run a campaign of fear to deter teenage girls from becoming pregnant, according to newly published files. Education Secretary Sir Keith Joseph wanted the Government to produce a series of 'scare' films in an attempt to curb the number of pregnancies among immature adolescents from 'the least good homes'. Joseph - one of Mrs Thatchers closest Cabinet allies - believed a 'sharply rising trend' of bad parenting was a 'major cause of poor education and crime', and he had no doubt who was responsible, according to official papers released by the National Archives under the 30-year rule. Allies: Mrs Thatcher (left) was told by her then Education secretary Sir Keith Joseph (right) that the government should produce a series of 'scare' films in an attempt to curb the number of teenage pregnancies. 'The young concerned tend to be the least mature from the least good homes. They embark on parenthood casually,' he wrote in a memorandum to Thatcher, dated October 1982. 'Those girls who are at most risk will tend neither to restrain themselves nor insist on or use contraceptives nor to have sufficient grip even to consider abortion in sufficient time.'His solution, he acknowledged, would be controversial. 'The young concerned tend to be the least mature from the least good homes', Thatcher was told in 1982. 'One possibility - delicate and fraught with risk - would be to try to use, in connection with pregnancy, the approach used in connection with cigarette smoking - that is fear,' he said. Joseph - sometimes dubbed the Mad Monk - reminded Thatcher that when he was a minister at the Department of Health and Social Security he approved a series of four short films to try to scare people off smoking. 'They were widely noticed. Some of the most vulnerable may have been influenced because the films used hedonistic and short time-horizon arguments. 'We could therefore explore whether short scare-films, suggesting that maternity is marvellous when the parents concerned are ready for it, might be practicable.' His comments echo a controversial speech he made eight years earlier when he claimed that single mothers 'who were first pregnant in adolescence in social classes 4 and 5' were threatening the balance of 'our human stock'. His words, in 1974, raised the spectre of eugenics and were widely seen has having cost him the chance of the Tory leadership. Instead he urged Thatcher to stand.

in: Anyone who’s ever been stuck on a train must have thought this at least once: maybe it would be quicker on foot. James Heptonstall did more than just wonder – he got up and ran like the clappers. In a daredevil challenge of man versus machine, the 30-year-old England touch-rugby player burst out through the train’s open doors, sprinted fearlessly up flights of steps and belted through city streets in an attempt to beat it to the next stop. Scroll down for video. Ready, set, go! As soon as the doors open, Mr Heptonstall is captured charging out of the doors (left) by his friend Noel Carroll. Footage from the GoPro camera on his head shows him running up the station's stairs. The race is on: GoPro footage shows Mr Heptonstall running through the streets towards Cannon Street Tube station, where he makes it to the carriage (pictured right) just moments before the doors close. Somewhere beneath him, the London Underground train he had just abandoned at Mansion House had already begun to clatter and trundle its way eastwards on the Circle Line, unhindered, and running perfectly on schedule. Had this been a Superman movie, our hero would have been billed as ‘Faster than a speeding train…’ Mr Heptonstall, however, had yet to cross the finish line. But what’s this? Above ground at Cannon Street, a panting young environmental consultant from Hampstead, dressed in shorts and running gear, comes skidding through the ticket barrier at high speed. He swipes his Oyster Card to get through. He leaps down the steps so fast he almost tumbles into the wall. In the carriage he vacated one stop earlier, all eyes are now on the platform entrance as the train doors are about to close. Waiting: Mr Heptonstall is seen standing behind closed doors as the tube carriage leaves Blackfriars station. First obstacle: Footage taken  on a GoPro camera shows him rushing through the first set of ticket barriers. Leaving the station: Before he bounds up the stairs that lead from Mansion House station to the street. Sprint: A map shows the route Mr Heptonstall took between Mansion House and Cannon Street stations. And then he appears! With a dramatic, triumphant lunge, he hurls himself back into the carriage – cheered and applauded by the same passengers who had watched him depart. Mission accomplished… with less than two seconds to spare. Now his Race The Tube video, filmed on a miniature camera strapped to his head, is becoming a favourite on YouTube and a talking point among weary Underground travellers across the network. Mr Heptonstall completed the 415-yard, platform to platform sprint in 1min 18secs. He clocked up an average speed approaching 11mph, on a route that included having to negotiate two ticket barriers and scale or descend 75 steps. The train took 1min 20secs to travel along 339 yards of track, timed from the moment its doors closed at Mansion House and opened at Cannon Street. Footage inside the carriage was taken on a second camera operated by his friend Noel Carroll. Video from Epic Challenges. On the street: Another friend films Mr Heptonstall as he sprints between the two stations in the City of London. Clock is ticking: Mr Heptonstall races down one street before setting his sights on the Tube station. Last leg: With the station just feet in front of him, Mr Heptonstall keeps up the pace as he continues the sprint. Destination: Video taken by a camera attached to Mr Heptonstall's head shows him running into Cannon Street. ‘At first the other people on the train didn’t really know what was going on,’ he said. ‘I did get a few suspicious looks, although to be fair, I was wearing sportswear with a camera strapped to my head. I belted out as soon as the doors opened and Noel explained to the carriage what we were trying to achieve. After that, they were all waiting on tenterhooks.’ His spectacular re-entry to the carriage provoked delight and admiration – and secured a dozen or so impartial witnesses to verify his feat, should he ever need them. Mr Heptonstall was inspired to tackle the ultimately pointless challenge by others who had completed similar quests on European transport networks. He often uses the Tube to get to work but confesses he is not a huge fan. ‘Sometimes I just run,’ he said. Final push: Tension mounts after Mr Heptonstall enters Cannon Street Tube station and leaps down the stairs. Anxious: Passengers inside the carriage can be seen waiting for Mr Heptonstall to reappear at Cannon Street. Desperate: Film taken from Mr Heptonstall's camera shows his view of the waiting carriage as he runs. Nearly there: Passengers are waiting on tenterhooks as they wait to see whether he will make it. Made it! Mr Heptonstall collapses on the floor after running onto the carriage - seconds before the doors closed.
