Sir Alasdair retired from teaching in December and I am delighted that he has agreed to work with schools in Wales, initially to the end of the summer term.
Ymddeolodd Syr Alasdair o'i waith fel addysgwr ym mis Rhagfyr ac rwyf wrth fy modd ei fod wedi cytuno i weithio gydag ysgolion yng Nghymru, tan ddiwedd tymor yr haf i gychwyn.
