Thousands of pounds were “haemorrhaged” by Brighton traders due to a violent protest.

It is calculated traders suffered losses of £162,500 when March for England came to Brighton, on April 27.

A survey estimated losses from just over 100 businesses, but this could be the tip of the iceberg.

The controversial march was characterised by street violence and vandalism between nationalists and anti-fascist counter protesters.

One individual business reported a loss of £50,000 alone.

Around 35 businesses reported losses of between £100-£500, around 25 reported losses of £500-£1000 and some 20 reported losses of £1000-£2000 due to the protests.

Traders described an atmosphere of intimidation, violence and of a “no-go area”.

One said: “We made no sales on the day at all and believe that this was because of the march.

“I was concerned for the safety of my staff and in future do not feel I can ask them to work on that day.”

Another said: “The day was a disaster as people didn’t come into the North Laine area.

“We stayed open but it wasn’t worth it.”

Another added: “The city was jam-packed full of police and barriers.

“People don’t want to come to Brighton to see it look like a ‘no go’ zone!”

The survey was conducted by Brighton’s Business Improvement District (BID), also known as Brilliant Brighton, and commissioned by the Tourism Advisory Board.

Gavin Stewart, manager of Brilliant Brighton, said the march had become a “blot on the calendar” for the city.

He said: “With the policing costs also in the region of £500,000 alone, there is a need for some serious questions as to whether the city can realistically afford for this event to continue in future.

“Far from celebrating the country, the event creates a cultural vacuum, whilst haemorrhaging money from the local economy for the privilege.”

Soozie Campbell, chairwoman of the Tourism Alliance, said: “If MfE really are as patriotic as they claim then they need to recognise the damage they are doing to British businesses and call a halt to these marches.

“I have proposed they meet with the business community representatives to discuss alternative ways to celebrate St George’s Day.

“Let’s see if they genuinely want to celebrate or if they really just want to fight.”
