Protective boarding around the statue of Winston Churchill in Parliament Square is being removed ahead of the visit to London by French President Emmanuel Macron on Thursday.
The statue was boarded up, along with several others, after it was sprayed with graffiti during a Black Lives Matter protest prompted by the death of George Floyd in the US.
The words "was a racist" were written beneath the statue of the war time leader.
A spokesman for the Mayor of London Sadiq Khan, who ordered the hoarding to be erected, said: "The covering around the Winston Churchill statue will be removed for the visit of President Macron to London."
In the wake of the daubing, some far-right groups urged supporters to defend the statues, and a subsequent Black Lives Matter protest in London was cancelled as a result over fears of violence.
On Saturday several thousand people arrived in Parliament Square to do so, although the afternoon quickly turned violent.
Glass bottles and fireworks were thrown at police and a small group of Black Lives Matter protesters.
Last week Emma Soames, the granddaughter of Churchill, said his statue in Parliament Square may have to be moved into a museum if protests continued.
She said she had been "shocked" to see the statue being boarded up, although she understood why it had been necessary.
While she acknowledged some of her grandfather's views would be considered unacceptable today, she said he was rightly seen as a hero by millions of British people.
"He was a powerful, complex man with infinitely more good than bad in the ledger of his life," she told the BBC Radio 4 Today programme.
"Until now he was regarded as the saviour of this country and one of this country's greatest democrats and parliamentarians. That is why the statue is there.
"People weren't looking at the entire record of people when they put up statues to them. If they did, we would be living in a country of empty plinths, I think."
She added that it was "extraordinarily sad that my grandfather, who was such a unifying figure in this country, appears to have become a sort of icon through being controversial."
The furore surrounding the Churchill statue also followed the toppling of slave trader Edward Colston's statue in Bristol by protesters at a Black Lives Matter rally sparked by the horrific death of black man George Floyd in the US.
The downing of Colston's statue has sparked a debate of how the UK acknowledges its imperial past and links to the slave trade, with the future of some other monuments called into question.
