Tottenham manager Harry Redknapp has gone on trial accused of receiving offshore bungs from his former employer.

The 64-year-old – tipped as a future England boss – dodged taxes on “substantial payments” while he was in charge at Portsmouth, a jury heard.

Appearing in the dock, Redknapp stood accused of receiving two untaxed payments of more than STG189,000 from former chairman Milan Mandaric, his co-accused.

John Black QC opened the Crown’s case at Southwark Crown Court by telling jurors “both parties must have known” they were avoiding taxes.

“These payments were a bung or offshore bonus that the parties had absolutely no intention of paying taxes for,” he said.

Redknapp’s “widespread popularity” was singled out by the prosecution.

“He is currently enjoying what may be described as footballing success,” Mr Black said.

“They (Tottenham) are currently riding high and are placed today as third in the league despite yesterday’s result.”

Redknapp is “unusually talented”, the Crown said.

Redknapp, appearing behind bullet-proof glass alongside Mandaric, read notes as Mr Black outlined how the manager received player transfer bonuses under a clause in his contract.

Mr Black focused on the purchase of Peter Crouch for STG1.25 million before he was sold for STG4.5 million.

Redknapp and Mandaric deny two counts of cheating the public revenue when he was manager of Portsmouth.

The first charge alleges that between April 1, 2002 and November 28, 2007 Mandaric paid $US145,000 into a bank account held by Redknapp in Monaco to avoid paying income tax and National Insurance.

The second charge for the same offence relates to a sum of $US150,000 allegedly paid by Mandaric to the same account between May 1, 2004, and November 28, 2007.

Redknapp, who underwent minor heart surgery last year to unblock his arteries, is the most successful English manager in the modern game, having led Portsmouth to FA Cup success and Spurs to last season’s Champions League quarter-finals.

Serbian Mandaric, 73, is chairman of Sheffield Wednesday, having previously worked at Leicester.

Redknapp, of Panorama Drive, Poole, Dorset, is represented by John Kelsey-Fry QC, while Lord Macdonald QC is counsel for Mandaric, of Stretton Hall, Oadby, Leicestershire.

Redknapp was described as a “hard-headed businessman” as the jury of eight men and four women were shown a string of documents and his signature.

Bonuses paid to Redknapp during his time at the club would total up to STG500,000 depending on profits the club made on player transfers, Mr Black added.

“Harry Redknapp was, it goes without saying, no ordinary employee,” Mr Black said.

He had the “greatest capacity to influence the success or failure of his football club”, he said.

The barrister said: “Talented and popular he might have been, the Crown say he was nevertheless a hard-headed businessman, with a financial acumen and pecuniary sense of his influence to his employers.”
