OG, If Nigel Farage had made an admission to the THEFT of £200 000 he would have been, arrested, interviewed and then upon advice from the Crown Prosecution Service, either charged or released without charge due to insufficient evidence.The fact that you trust a man who admits to stealing £200,000 pounds from accommodation expenses makes your judgement of character highly subject, and his trustworthiness none existent.
His excuse "others do it" with that attitude he is capable of anything.
Each stage of the above process requires a certain level of suspicion. The police will, if they suspect that an offence has taken place and they suspect that a person is guilty of that offence, arrest that person. An admission to the theft of £200 000 would more than satisfy the level of suspicion required to arrest Nigel Farage. As far as I am aware, he has never been arrested, interviewed, charged or gone on trial for the offence that you allege. We already know that where genuine theft and corruption occurs, politicians do go on trial and they do go to gaol. This has not happened in the case of Nigel Farage because no theft has occurred.
Again, you are transitioning straight to the far end of the scale and not applying any measure of restraint or reason. Farage, MAY have claimed every single scrap of allowance to which he is entitled and some may believe that to be excessive and greedy. I don't know, because I don't know what he has claimed. However, there is a million miles between this and an outright act of criminality in the form of theft.
I suspect that you are applying a similar process to BREXIT in that you are taking aspects of the process which MAY be mildly detrimental to the UK, but presenting them as catastrophic to your audience.
