A woman walks past a dual Irish-English language street sign on February 21, 2018 in Belfast, Northern Ireland. Talks to restore the Northern Ireland power sharing executive collapsed last week with the main sticking point being a proposed Irish language act. A leaked draft agreement between Sinn Fein and the DUP confirmed a three-stranded approach to the language question, which would have resulted in an Irish language act, an Ulster-Scots act and a so-called respecting language and diversity act. The province has been without a government for over 13 months since then deputy First Minister Martin McGuinness resigned his position in protest at a botched renewable heating scheme.
