She is attending the Balmoral Show in Co Antrim
British Prime Minister Theresa May has made a surprise visit to Belfast.
She is attending the Balmoral Show - the largest agricultural event in Northern Ireland.
It is thought to be part of Mrs May's general election campaign, where she will visit every area of the UK.
However some local politicians are not happy with the trip.
SDLP MLA Daniel McCrossan tweeted: "Theresa May couldn't fly to NI for talks process or to try save our institutions, but finds time to visit the Balmoral show! Ridiculous PM!"

It comes amid fraught tensions between London and Brussels.
Earlier this month, a German newspaper reported a disastrous Brexit meeting between UK and EU representatives.
According to the newspaper, EU officials were amazed at Mrs May's suggestions that the concerns around the status of EU and UK citizens could be sorted at a European Council meeting in late June.
Mr Juncker is said to have produced piles of paper over the CETA trade deal with Canada and Croatia's EU membership agreement to illustrate how complex any Brexit deal will be.
Mr Juncker and Michel Barnier - the EU's chief Brexit negotiator, who was also in attendance - were described as having been astounded by their host's suggestion that the UK did not have to pay "a penny" of the Brexit divorce bill.
The visit also follows a royal visit to Ireland by Prince Charles and his wife Camilla, which saw them meet President Michael D Higgins and Taoiseach Enda Kenny.
