Peter Robinson Completes Campaigning For The DUP

BELFAST, NORTHERN IRELAND - MAY 6: DUP east Belfast candidate, Gavin Robinson (L) out canvassing for votes on the last day of the campaign on May 6, 2015 in Belfast, Northern Ireland. Many political observers have predicted that the expected 8-10 DUP Westminster seats could have a key role in deciding who will form the next government if the general election results in a hung parliment. In anticipation of the important role the party may play the DUP has already outlined their demands from a potential government partner and hasn't ruled out working with Labour or the Conservatives.
