Tommy Robinson and pro-Trump marches prompt fears of violent clashes in London

Police will be flooded into central London on Saturday amid fears two protest marches – one in support of jailed far-right leader Tommy Robinson, the other welcoming US president Donald Trump – could combine and turn violent.
Specially trained officers will patrol the processions after a previous demonstration in support of the EDL founder saw metal barriers and bottles being thrown at police.
Scotland Yard has already imposed restrictions on where the protestors can go “in order to prevent serious disorder and disruption to Londoners”.
A spokesperson said the two groups would be allowed to come together for a series of speeches in Whitehall – but would be kept apart before then.
He said: “Both events are due to take place on Saturday and the conditions have been imposed due to concerns of serious public disorder and disruption to the community.
“A recent event involving the Free Tommy Robinson group on 9 June resulted in serious violence in central London.
“A significant policing operation will be in place for the duration of both events on 14 July, which is designed to prevent trouble from flaring up and facilitate peaceful protest.”
Conditions set under the Public Order Act state that pro-Robinson protesters must march from Temple Place to Whitehall along a pre-set route, while Trump followers will arrive at the same destination from the American Embassy.
Republican Congressman Paul Gosar and controversial Dutch populist Geert Wilders are among those expected to address the crowds once there.
Police are also restricting the movements of a Unite Against Fascism march to Parliament Street and nearby, to ensure the two ideologically-opposed groups do not clash and to “prevent intimidation”.
Robinson is currently serving a 13-month prison sentence for contempt of court after breaking reporting restrictions on a trial at Leeds Crown Court.
Jeremy Corbyn joined anti-Trump protesters as they took over central London with more than 250,000 people taking to the streets. 
Police told MailOnline four people have been arrested at the demonstration as they urged members of the public to stay away from Trafalgar Square as the area reached full capacity. 
Scuffles broke out near Whitehall earlier today as tempers flared between pro-Trump supporters and campaigners.  
A spokesman for the Met said so far four people had been arrested for common assault and attacking a police officer. 
There were many familiar faces among the crowds including Labour leader Jeremy Corbyn who used the opportunity to deliver a speech to the tens of thousands. 
The Labour leader told crowds that the PM should not have 'rolled out the red carpet' for the US president after his treatment of immigrants and jibes about the NHS and crime levels.
But Tory MPs pointed out that Mr Corbyn previously invited IRA activists to Parliament in the aftermath of the Brighton Bombing and has praised extremist group Hamas.
