Queen Elizabeth II held a state banquet at Buckingham Palace in honour of the Mexican president's visit to London.

The president attended the banquet with his wife Señora Angelica Rivera de Pena.

Her Majesty made a speech at the start of the banquet, referring to the "long and enduring friendship" between the UK and Mexico: "We remain proud to have been the first European country to recognise Mexican independence. Ladies and gentleman, I ask you to rise to drink a toast to the president and Senora Rivera and to the people of Mexico."

The scandal has created a major headache for Nieto, who took office two years ago pledging to end a wave of gang-related violence that has killed around 100,000 people since the start of 2007.
