Have the Lib Dems heard of Devolution?

Mark Young, Parliamentary Candidate for the Lib Dems in the Vale of Clwyd, proudly informs us that the Welsh Liberal Democrats have succeeded in having a petition accepted on the, patently useless, Petitions to the Prime Minister site.

It is a very laudable petition:

http://petitions.pm.gov.uk/better-parking/

We the undersigned petition the Prime Minister to Create a new
target, which will encourage NHS Hospitals to create adequate
car parking spaces.

Many Hospitals have insufficient car parking spaces. Patients,Visitors, Staff, out-patients have to queue up for scarce and insufficient car parking spaces.

Visitors may be charged two pounds for visiting a relative in the afternoon, and a second charge of two pounds for visiting in the evening.

Can the Government please encourage NHS hospitals to increase the number of car parking spaces. At the same time, introduce fair and reasonable concessions for those customers who are unable to afford some charges.

However shouldn't a Welsh Liberal Democrat parliamentary candidate be expected to know that hospital parking is a devolved issue, and that the National Assembly has its own Petitions System?
