3. SOUNDBITE (English) Majella Maguire, reveller:
"It just means fond memories of my childhood celebrating with my parents, at school. We'd wear our little Irish flags and my grandparents, it just reminds me of everything I grew up with so it's really really lovely."
4. Cutaway of James Campbell, a Londoner from County Mayo in Ireland
5. SOUNDBITE (English) James Campbell, reveller:
"Oh, the atmosphere is brilliant, we live in north London so we get the train down here for the parade. We try an get here a bit early so we go inside and look at all the stalls and all the stuff from Ireland so it's all pretty good and all the floats, the kids love the floats."
6. SOUNDBITE (English) Rachel McManus, reveller:
"Well I've been celebrating St Patrick's day since I was little because my dad's Irish and my sisters and brothers are Irish. I was born in London but I will still go out and celebrate it because it is just a family tradition. We do it every year. We'll go out and go to the parade or sit around at home and celebrate it. It's something we've been doing since we were kids."
Thousands of people have lined the streets of Central London on Sunday (17 MARCH 2019) to mark St Patrick's Day in the British capital.
Donning green clothing and shamrock decorations, the crowd watched the annual parade, which was followed by a concert in Trafalgar Square.
This year's march has taken place amid a new set of questions about relations between the United Kingdom and Ireland as Brexit negotiations hit a standstill.
British politicians are struggling to find a way to exit the European Union without disrupting the two-decade old peace accords that created an open border between the Republic of Ireland, which is in the E.U., and Northern Ireland, which is in the UK.
