invoice

Based on invoices and bank statements seen by Panorama, it is understood SHE spent about £20,000 on building work and business start-up costs for Kiwi Beverages.

"That included setting up temporary parking infrastructure for over 12,000 people, setting up barricades, setting up temporary lighting and hiring a towing company. The invoice we sent the campaign reflects that."

Ms Gallagher was sent an invoice demanding the money be returned but was subsequently sent an email stating the invoice was sent in error.

But after it was delivered to a warehouse on the outskirts of London, the invoice was not paid.

Bank statements, payslips, tax invoices, anything that European embassies required to prove that people applying for student, or work, or business visas had the necessary funds to ensure they planned to return to Vietnam.
