Donald Trump is to make a speech on immigration on Wednesday in Arizona which could define his presidential campaign.

Immigration policy has become the cornerstone of his election speeches and some of his statements have caused huge controversy in America and around the globe.

He has continually stated he will construct a wall between the US and Mexico and even suggested the creation of "deportation squads" to tackle the issue of undocumented immigrants in the country.

On Sunday, his running mate, Mike Pence, outlined how Trump's stance has never wavered and expected concrete policy announcements on the topic in the coming weeks.

It appears that Trump will act sooner and will clarify his position in Arizona this week. The state borders Mexico yet hasn't voted for a Democratic presidential nominee since 1996, when Bill Clinton took the state.

Then, there were under 1.3 million votes cast in the election whereas in 2012, 2.2 million took to the polls. The state has 11 electoral college votes of the 270 required to win.
