Some Welsh Labour activists are angry and frustrated that an unnoticed party rule change may result in a sitting MP getting a new seat without a contest.
Boundary changes expected to be ratified by Westminster in July will see the number of constituencies in Wales reduced from 40 to 32. This will result in significant alterations to the make-up of every seat in Wales, except Ynys Mon, which has been awarded special status and will continue to exist in its present form.
In south east Wales, the existing seats of Caerphilly and Islwyn are among those that will disappear. According to the final proposals from the Boundary Commission for Wales, a larger Caerphilly seat will be created while most of Islwyn - once held by former Labour leader Neil Kinnock - will be merged with Newport West to form a new seat called Newport West and Islwyn.
