Martin McGuinness calls on Arlene Foster to 'step aside' for energy scheme probe

Northern Ireland's Deputy First Minister Martin McGuinness has called on First Minister Arlene Foster to "step aside" to allow an investigation into a controversial green energy scheme.

Mr McGuinness said he told her over the phone he was seriously concerned about allegations around the eco-friendly initiative that has left Stormont facing an estimated £400m (€477m) overspend.
