Marine Le Pen has visited Trump Tower during an unannounced visit to New York.

The far-right French Front National leader has consistently praised Donald Trump and is currently in New York just four months before the French presidential elections, in which she has emerged as a frontrunner.

Ms Le Pen was spotted by journalists at Mr Trump’s headquarters but it remains unclear whether she met with the businessman or his advisers.

The President-elect's spokesman, Sean Spicer, told CNN that the neither Mr Trump nor any of his team were scheduled to meet with the French politician. Trump Tower is open to the public, he added.

Pictures on social media showed Ms Le Pen holding a meeting with three men in what appeared to be a public area of the building. One of the men is believed Louis Aliot, her partner and one of the Front National's vice presidents,

The French politician's chief of staff was quoted as saying the trip to New York was a “private visit” and would only reveal that a meeting with Mr Trump was “not on her public agenda”. Ms Le Pen refused to confirm to journalists at Trump Tower whether or not she was meeting the President-elect.

She has previously called Mr Trump's election “a sign of hope” and said the Republican was “putting in place measures I have been demanding for years”.

Speaking to CNN late last year, she said: “Donald Trump has made possible what was presented as completely impossible. So it’s a sign of hope for those who cannot bear wild globalisation. They cannot bear the political life led by the elites.”
