Before the tragedy happened, a former Prime Minister and the current leader of the Labour party have added their voices to the Brexit debate, calling on the public to vote to stay in the European Union.

Gordon Brown, Labour prime minster from 2007 to 2010, said if the UK chose to leave the EU, it would face an unemployment crisis.

Labour leader Jeremy Corbyn also expressed misgivings, saying leaving was not the solution to the immigration crisis and that the benefit of taking in migrants far outweighs the disadvantages.

"For my answer to the mother and father worried about the future of their children and the jobs they can have, is that the biggest job creator over the next ten years is going to be the single market of EU and we must be there. If we are going to defend and protect the right of everyone to have a fulfilling job during the lifetime," Brown said.
