A family that deprived Royal Mail of £70 million over a decade owned a “multi-million-pound mansion” and bought properties “like Donald Trump,” a court has heard.

Parmjeet Sandhu, 56, and his nephew Balginder Sandhu, 46, were part of a scheme to under-declare mail posted through a network of logistics companies in Buckinghamshire and Berkshire, pocketing millions of pounds, it is alleged.

The trio appeared for trial at Southwark Crown Court, central London, on Wednesday (August 16) charged with conspiracy to commit fraud by false representation between 2008 and 2017.

Prosecutor Ellis Sareen said Narinder Sandhu lived with his family at Hadley Grange, a “multi-million-pound mansion” near Beaconsfield, Bucks.

“Narinder Sandhu and his wife Jaswinder had a multi-million-pound home, a Bentley, a Rolls Royce and a pool house,” Mr Sareen continued.

Sandhu’s declared taxable income was about £1 million per year towards the end of the period that the fraud was running, the prosecutor said.

Mr Sareen said “thousands” of items were under-declared by manipulating docket spreadsheets.

He said they “exploited and manipulated” a self-declaration system used by large postage firms and in some cases paid half of what they should have for the mail posted.

While completing some invoices in 2012, Balginder Sandhu remarked “how rich” his alleged co-fraudster Lakhwinder Sekhon was getting.

In a message, Sandhu said: “Mans is smashing it… U keep making big bux.”

Sekhon replied: “Hahaha… Coming from a man buying properties like Donald Trump.”

Balginder Sandhu’s declared income rose from £30K for the 2008/09 tax year to £350K in 2013/14, which he used to buy properties, Mr Sareen said.

His uncle, Parmjeet Sandhu, operated from a warehouse in Slough, Berkshire, where his companies were based, while Balginder was also “integral” to the scheme, it is alleged.

He had an income of almost £100K a year on average in the tax years 2014/15 to 2016/17, the prosecutor said.

By 2016, so many companies were being operated by the group they were “starting to forget” where they were located, Mr Sareen said.

The fraud was only discovered when Royal Mail customers said competitors were offering unrealistic rates.

When investigators became suspicious about the group’s companies, all of their mail was diverted and checked, at which point it was found their postings had been “significantly under declared,” the prosecutor said.

Police warrants were issued in 2017, and the alleged fraudsters were arrested, the court heard.

Mr Sareen continued: “This has cost Royal Mail about £70 million or a little more.

“(The defendants) have not pocketed £70 million, but they have benefited.”

The three deny the charges and the trial continues.
