Hertford & Stortford MP Mark Prisk is to stand down at the next election.
In a letter to constituency chairman Alex Curtis, Mr.Prisk wrote: "I have decided not to seek re-election at the coming General Election. This has been a difficult decision, but I have always believed that if you seek election it must be whole hearted and that you should be committed to serve a whole five year parliament. I cannot make that committment".
"This decision is personal and is not in reaction to Brexit"
"I do, however, lament the wider decline in public discourse and the rise of narrow ideology over pragmatic, common sense."
