Nick's view on how boundary changes would affect Wales

A new Parliamentary map outlining plans to cut the number of Welsh MPs by more than a quarter has been published.

The number of Welsh seats in the House of Commons would fall from 40 to 29, with the size of Westminster constituencies increasing.

The new constituencies have been drawn up by the independent Boundary Commission for Wales under a formula set down under the previous Tory-Lib Dem coalition government.

BBC Wales political editor Nick Servini explains why Welsh MPs are facing more change than politicians representing other parts of the UK.
