A row has broken out over suggestions that a statue should be built in honour of former prime minister Margaret Thatcher.
One of the suggested sites is London's Trafalgar Square, where thousands of anti-Thatcher supporters are set to hold a party on Saturday evening.
Len Duvall, leader of the Labour group on the London Assembly, said it would not be appropriate to have a statue of Baroness Thatcher in the central London square, which was the scene of riots over the poll tax when Mrs Thatcher was PM.
He said: "She was a significant figure, but she was a divisive figure. I would argue that Margaret Thatcher did great harm to many people in London, and to place a statue of her at the site of the poll tax riots, which symbolised just how divisive she was, would be crass triumphalism.
"This would also mean the fourth plinth would not be available for future artworks, which has been hugely successful and popular."
A number of protest groups are planning to take part in Saturday's event, following a series of impromptu celebrations in towns and cities across the country after news of the former prime minister's death on Monday.
Conservative politicians have called for a commemorative statue for Baroness Thatcher.
