Democratic debate as it happened: Clinton and Sanders face off in Miami before the 15 March primaries

That's a wrap for our live coverage of tonight's debate. Be sure to come back tomorrow for the GOP debate with Donald Trump, Ted Cruz, Marco Rubio and John Kasich.

Time for closing remarks:

• Clinton: Thanks for a lively debate. Says she has a plan to take down the economic, education and health care barriers. Says she will find common ground but will stand her ground. Honoured to have the support of Floridians on 15 March.
• Sanders: Wonderful debate but several issues not discussed. Talks about unequal wealth distribution.

Next: Puerto Rico and whether either candidate will help the island territory to restructure its debt within the first 100 days in office.

• Clinton says absolutely she would, but says she hopes that it will get done before she is elected to office.
• Sanders blames vulture capitalists for Puerto Rico's unsurmountable debt.

Moving on to questions on Latin America. First up is Cuba and the upcoming trip to the island nation by President Barack Obama. Clinton says meeting with Cuban dissidents is "important" and says it's crucial to have the Cuban people move towards a democracy.

Sanders, meanwhile, says the US should end the embargo against Cuba and relations should completely normalise.

Sanders and Clinton have had several Trump-Rubio-Cruz interactions tonight. Exhibit A:

After fierce battle over how the candidates plan to pay for their education and health care plans, the conversation turns to climate change. Sanders calls for a political revolution, while Clinton lays out a plan on how to work with Republicans to move legislation forward.

Education is now on the docket. Specifically tuition free higher education and refinancing student debt. "We're gonna refinance everyone's student debt. Corporations can refinance their debt, under my plan you can also," Clinton said.

Sanders asked a key question: Why should voters vote for him [a career politician] over Clinton [an establishment politician]? The Vermont senator points out that he doesn't take money from corporations, among others.

Clinton is questioned about Benghazi and she once again has to clarify what she said to family and the public about the terrorist attacks.

I am not a natural politician, in case you haven't noticed, like my husband or President Obama.

-Hillary Clinton

Clinton is questioned about her past support for building up border security. Clinton owns up to her past votes on the issue, but says it is now time to focus on immigration reform.

She takes time to mock Trump for his proposals to build a "beautiful tall wall" that will "magically paid by the Mexican government".

Clinton is asked point blank if she can promise that she will deport children or undocumented immigrants that do not have criminal records. She says, "I would not deport children. I do not want to deport family members either."

As expected, immigration reform (particularly DACA and DAPA programmes) are being discussed. Sanders' is questioned about his past opposition to a bipartisan immigration reform bill that included guest worker provisions. The two go back and forth on who supports immigration reform the most.

The candidates are asked if Donald Trump is a racist. Both spoke vehemently against him and maintain that a nominee who speaks out against so many groups will never be elected.

Talk turns to Clinton's email scandal. However, before delving into the issue Jorge Ramos clarifies that his daughter works for Clinton's campaign. Ramos asks Clinton if she will suspend her campaign if she is indicted.

Clinton maintains that it was a mistake to use her private email server but maintains she never sent emails that were classified at the time.

Clinton is asked about what went wrong in Michigan, where Sanders' pulled a surprise win. The leading Democratic candidate said that she sometimes win close races and sometimes she loses. She instead focuses on her win in Mississippi.

And we're off. Univision's Jorge Ramos and Maria Elena Salinas introduce the two candidates in Spanish. The debate, which is being simulcast on CNN is being dubbed in English. It's unclear if it will be dubbed the entire night.

Welcome to our live coverage of the eighth Democratic debate, which is broadcasting live from Miami, Florida. The remaining two candidates are just days away from several major primaries on 15 March, including one in The Sunshine State.
