When the United Kingdom’s Prime Minister David Cameron meets next with Mexican President Enrique Pena Nieto, he will "raise concerns" about human rights and discuss Mexico's judicial system.

President Pena Nieto, who attended a state banquet hosted by the Queen on Tuesday, is in the middle of a three-day state visit to the United Kingdom.

Commenting about the upcoming meeting between the Prime Minister and the Mexican President, a spokesman for Mr Cameron, as reported in a BBC article stated that, "You can expect the prime minister to raise concerns that have arisen with regard to human rights and the judicial system in Mexico.”

Noting that the U.K. has raised concerns before and will continue to raise them, the spokesman added that the questions would be brought up “in the spirit of collaboration that we have with the Mexican government and the Mexican authorities."

Mexico has been receiving worldwide criticism for its perceived political corruption and inaction in the face of dangerous drug cartels.

The global human rights watch group Amnesty International said that, in Mexico, torture was "out of control" and has denounced the Mexican police and security services as having "blood on their hands."

According to Amnesty International, as reported in the BBC, more than 100,000 people have been killed and more than 22,000 have disappeared since Mexico launched a "war on drugs" in 2006.

Most recently, Pena Nieto, who has had to field accusations about economic improprieties, has faced growing public rage over the handling of the abduction and apparent murder of 43 student teachers.

Prosecutors involved with the case say that the students were arrested by corrupt police officers who handed them over to a gang to be killed.

The Queen spoke, while welcoming Nieto and his wife Angelica Rivera at a Buckingham Palace banquet, of the "enduring friendship" between the U.K. and Mexico.
