Given how adamant the current Prime Minister of the UK is that he will not ask the EU for another extension under any circumstances and that it is now enshrined in law that the PM must seek an extension to prevent a no deal Brexit on 31st October if a no deal hasn't been explicitly approved by parliament.
In these circumstances is the current PM likely to face a criminal investigation and prosecution in the UK law system if he does not comply and if so how likely would he be to face jail time if a prosecution where to take place?
