Protesters are coming from far and wide in a show of strength against the government's austerity measures on Saturday (June 20), in what is expected to be one of the largest rallies in recent history.
Coaches have been put on to bring people from around the country, and organisers saying there could be hundreds of thousands of people taking part. The protest will begin outside the Bank of England at 1pm, before moving towards Parliament Square, where a rally is expected to take place from around 2:30pm until 5:30pm.
As well as the many ordinary people who are fighting spending cuts being implemented by the government, there will be plenty of familiar faces. Here's some of the big names that are expected to take part.

Public services cost 100s of billions to fund but I doubt it would encourage the richest in this country to get a conscience and follow suit— Charlotte Church (@charlottechurch) June 4, 2015
I have no ulterior motives. The injustice and inequality in society that is pushed further by this government makes me as angry as the hulk!— Charlotte Church (@charlottechurch) June 4, 2015
