DUP Leader Sir Jeffrey Donaldson has written to the Prime Minister urging him to scrap controversial legislation to address the legacy of Northern Ireland's Troubles.
Sir Jeffrey said that an "amnesty for terrorists is not only an affront to justice but a gateway to further attempts to rewrite and airbrush the past".
Speaking in the Commons on Wednesday, Northern Ireland Secretary Chris Heaton-Harris said he did not think he would ever be able to persuade the DUP to support the Bill.
