Thousands of protesters are expected to gather in front of Downing Street on Monday evening to protest Donald Trump’s immigration ban.

The executive order has sparked global outcry after the US President blocked immigration from seven Muslim-majority countries and suspended refugee settlement in the country.

Refugees, green card and visa holders were blocked from boarding US-bound flights or detained in arrivals over the weekend, causing protesters from across America to descend on international travel terminals in outrage.

And as unrest reaches fever-pitch in the US, anger is spilling over across the pond.

A petition calling on Theresa May to axe Mr Trump’s planned state visit to the UK reached one million signatures on Monday.

Tonight's “emergency demo” is expected to attract thousands to protest “UK complicity” in the measure.

Here’s everything you need to know:

When is it?

According to the event page, the protest will be held on 30 January 2017 from 6-8pm GMT.

Where is it?

The precise location is 10 Downing Street, SW1A 2AA, London, however with more than 20,000 expected to attend, it will likely spill out into surrounding areas.

How do I get there?

The closest tube station, roughly eight minutes walk away, is Westminster - served by the Circle, District and Jubilee lines. Charing Cross, served by the Northern and Bakerloo lines, is 10 minutes away on foot.

Who will be speaking?

Speakers are expected to include: Baroness Shami Chakrabarti, Ed Miliband MP, Baroness Sayeeda Warsi, Caroline Lucas MP, Wail Qasim (Black Lives Matter), Tim Farron MP, Mhairi Black MP, Lily Allen, Clive Lewis MP and Bianca Jagger.

A number of humanitarian groups will also be in attendance and several charity heads are expected to address the crowds.

Why should I attend?

Many were outraged at the UK Government’s slow response to condemn the “Muslim ban”, after leaders in Canada, France and Germany all spoke out against the measure.

The event titled: “An Emergency demo against Trump's #MuslimBan and UK complicity,” gives Britons an opportunity to “stand in solidarity” with American protestors.

“Theresa May has decided to ally herself with Donald Trump's bigoted, misogynistic government. She has refused to speak out against Donald Trump's #MuslimBan,” event organisers wrote.

“Ms May has betrayed her own people. That doesn't mean we have to. Let's stand in solidarity with those targeted by Donald Trump's hateful government, including the people of this country, outside Downing Street and all over Britain.”

How else can I show support?

Humanitarian groups started to act as soon as the order was implemented, and many still require urgent funding to continue challenging the measures in court.
