2. Various of people holding signs (Spanish) "Eurocitizens. British citizens in Spain, Spanish citizens in the UK - for our rights, for our future."

4. SOUNDBITE (English) Angela Owen, teacher and UK citizen in Spain:
"I'm here today because I'm protesting about the Brexit, which I disagree with totally - as most people do with any common sense - and also for the fact that it was an injustice. We (UK citizens abroad) weren't allowed to vote in the referendum because we are in Spain, which I find is very unfair because if they had asked all the 'expats' in Europe to vote, Brexit wouldn't have won."
5. Wide of people
6. SOUNDBITE (English) Diana Greatland, retired UK citizen in Spain:
"We are very unsure and very unhappy about our situation here in Spain, because we don't know what is going to happen to us. It's not so bad for me, because I'm retired, but for my daughter and her family, I don't know. She has a job here, but if she is out of the European Union maybe she will lose her job. I don't know."
7. Various of demonstration
8. SOUNDBITE (Spanish) Angel Satuen, lawyer:
"We are celebrating that we are all together, even though the Europe of 28 (member states) is dead, the 27 are very much alive. There is a big desire of unity because that's why Europe (EU) was born - for unity based on reconciliation and solidarity, and for a stronger Europe in the world. A global world."
9. Close of sign reading (English) "I'm not a bargaining chip."
10. SOUNDBITE (English) Fiona Wespri, translator and UK citizen in Spain:
"We feel we are British, as Scots, and Britain is taking us out of European Union and that shouldn't be. And there most be another referendum. I don't know if we will be able to vote because we live here, but I hope we do, and I don't think the decision will be the same this time."
Almost a hundred Spaniards and Brits joined together in Madrid on Saturday to urge lawmakers to protect the rights of citizens following the UK's exit from the European Union.
They made their case as part of a gathering to celebrate the 60th anniversary of the EU's foundation.
The EU anniversary comes four days before the British government plans to trigger negotiations to break from the 28-nation bloc after the country voted to leave in a referendum in June.
On Wednesday, the EU's chief Brexit negotiator said that failure to reach an orderly agreement on the UK's exit could leave four million European and British citizens uncertain about their rights and future.
Many of the protesters of British nationality residing in Spain have shown their discontent amid mounting concern over their future rights.
