FILE - In this Thursday, April 11, 2019 file photo, Northern Ireland Democratic Unionist Party leader Arlene Foster, center, speaks to journalists after her meeting with European Union chief Brexit negotiator Michel Barnier at EU headquarters in Brussels. The Democratic Unionist Party is a small Northern Irish political grouping with an outsized Brexit role. British Prime Minister Boris Johnson most likely needs the 10 votes the party has in Parliament if he is going to have any chance in getting any Brexit deal he negotiates with the European Union over the line. Little wonder then, that the party is being courted intensely by Johnson. As things stand, it’s not clear whether the party will support any deal that emerges.(AP Photo/Francisco Seco, File)
