An activist in Lincoln's Inn Fields about an hour before the start of the "Kill the Bill" march in London.

Several thousand people marched across central London to demonstrate against a law being passed by Britain's parliament that would effectively outlaw many protests, increase penalties for certain types of protest such as blocking roads and give the police far greater powers to stop, search and arrest. If such measures had been in place over the last 100 years they may have prevented the suffragette protests of the 1920s, the protests for greater welfare support in the 1930s, the black civil rights and anti-Vietnam protests of the 1960s, the early gay pride gatherings in the 1970s, the occupation of key locations by the Occupy movement and the more recent climate protests.

The bill will give the police new powers to ban demonstration deemed likely to be too noisy or a nuisance to a neighbourhood, to stop and search people without having to prove reasonable suspicion, new powers against 'unauthorised encampments' which travellers fear may be used against their communities and it will increase the maximum prison sentence for someone who destroys a memorial or statue from 3 months to 10 years.
