A politics teacher at a £31,000-a-year boarding school attended by Sir Winston Churchill has been banned from classrooms after he was caught on video exposing himself to a woman on a train. Nuku Vanonyi Cudjoe-Calvocoressi, 41, who was head of politics at St George's School in Ascot, was travelling on a Richmond to Reading train when he pulled up his shorts and exposed himself to a 33-year-old female passenger. He has now been banned from teaching for at least five years following a hearing by a National Council of Teaching and Leadership (NCTL) disciplinary panel in Coventry. Scroll down for video . Nuku Vanonyi Cudjoe-Calvocoressi, who was head of politics at St George's School in Ascot, was on a train when he pulled up his shorts and exposed himself to a female passenger (pictured) On June 30 2014 Cudjoe-Calvocoressi was convicted of indecent exposure at Berkshire Magistrates' Court following the June 13 incident on-board a train. The court heard at the time that he pulled up his shorts and exposed himself to her. The woman began secretly filming him on her mobile phone and asked her husband to meet her at Wokingham train station, where he confronted Cudjoe-Calvocoressi. Cudjoe-Calvocoressi left the station but was soon found and arrested by police and was charged with indecent exposure. When interviewed by police he initially denied that he had deliberately exposed himself, but when  he appeared at Berkshire Magistrates' Court he pleaded guilty to the offence. At the school's internal investigating meeting Cudjoe-Calvocoressi admitted that he had exposed himself - but said that he did not realise he was causing distress. Following the court case he was sentenced to a supervision requirement, a community order which runs until July 27 2017 and was ordered to pays costs of £85, compensation of £700 and a £60 victim surcharge. He was also told to sign the sex offenders register for five years. The woman filmed Cudjoe-Calvocoressi when he exposed himself on the train, leading to his conviction .

Now, at the NCTL disciplinary panel in Coventry Cudjoe-Calvocoressi admitted the alleged facts and admitted that the conviction was for a relevant offence. Imposing the ban on behalf of Education Secretary Nicky Morgan, NCTL official Paul Heathcote said: 'There is no allegation that his actions were sexually motivated and his actions did not involve children, nor did he use his professional position. 'While his actions had the potential to cause harm, there is no evidence that they did so. 'In all the circumstances I agree with the panel's recommendation that Mr Cudjoe-Calvocoressi be allowed to apply for the order to be set aside on or after 29 July 2019.' The ban means that he is prohibited from teaching and cannot teach in any school, sixth form college, relevant youth accommodation or children's home in England. He has the right to appeal to the High Court against the decision. However, the door has been left open for him to return to teaching. In a decision imposed on behalf of the Education Secretary it was held that Cudjoe-Calvocoressi should be allowed to apply to return to teaching in 2019 when the five-year order that he signs the Sex Offenders Register comes to an end.
