For years, the DUP wallowed in gratuitous attacks on the Irish language. Sammy Wilson called it a "leprechaun language". Gregory Campbell said Sinn Féin's entire wish list, which included an Irish language act, would be treated as "toilet paper".
In his speech on Saturday, Robinson is expected to renew his calls for greater co-operation between unionist parties. The East Belfast MP will say that "no party or personality should ever trump our shared strategic aims". "Under my leadership, we will be strong, but we will not be selfish," he will say in his speech. Pacemaker Robinson will again express support for being part of Northern Ireland's devolved government, saying "things happen" when DUP ministers hold office.
