Unfair competition

[browntrout]

Mrs BrownTrout has been running her own beauty salon in a smallish town for five years employing five staff. Most of the income comes from doing acrylic nails. The shop is still reasonably busy, but trade dropped off when a new salon opened nearby which is run by illegal immigrants from Vietnam. I've informed the border agency but nothing has happened. Most major towns have nail salons which are run by illegal immigrants from Vietnam, the border agency know this but the salons continue operating.

Yesterday she discovered another one is opening opposite her, again by illegal immigrants from Vietnam. They don't pay any income tax, NI, etc. and are usually a front for money laundering. Any ideas how to get them closed down?

I initially gave them the benefit of the doubt and wanted to believe it's a level playing field.

How do I know they're illegal immigrants from Vietnam?
Mrs BrownTrout is Vietnamese and phoned them asking for a job telling them she didn't have a visa it’s not a problem they don’t have one either.

There are thousand of illegal Vietnamese here. The two main trades are growing weed and running nail salons, even the person who is at the top is often illegal they just pay some who is legal to sign the lease (Mrs has been asked to do it in the past). The majority of the females who are here legally, are on the fiddle, single parents, free house, free money from the government and £500+ cash in hand doing nails.

If it was a legit business competing it's not a problem.

Back on track any ideas how to get them closed down.
