The representative of Mexico’s Querétaro state added: “It would be very simple for me to jump over into the United States, which shows how completely unnecessary and absurd it is to construct a $15bn wall”.

One of President Trump’s key election pledges was a wall along the 1,900 mile-long border between the US and Mexico to deter illegal immigration.

Just a few days after his inauguration, Mr Trump signed an executive order to begin constructing the wall.

Nevertheless, Mr Guerra Urbiola said he had climbed the fence to prove that Trump’s proposal was not viable.
