Me and my wife passed LIUK test in 2007, but it wasn't asked during our ILR application was granted in Feb 2012 due to HSMP-JR case.
Will LIUK test be still valid in 2013 when we will apply for naturalization

Is there any web site where we can find the test center as whether is it still providing services or not

I will be very thankful of any answers.
Kind regards
