A number of “suspicious” promotions and salary increases dished out unilaterally by the sacked PBS CEO John Bundy are being investigated by the broadcaster.

The salary increases, without board approval, were allegedly made when Mr Bundy was facing growing pressure from members of the Public Broadcasting Services board, who were calling for his resignation.

“A list of all the promotions and salary increases given by Mr Bundy during his time as CEO has been requested. These will all have to be reviewed after it transpired they were made without board approval as was his modus operandi,” one source said.

In some cases the salary bumps amounted to €10,000, backdated some five months.

PBS is particularly concerned about a raise given to members of the company’s senior management who had previously raised concerns about Mr Bundy’s decision making.

The former Labour Party TV personality, who switched over from the Nationalist Party several years ago, was ousted from his position at PBS last week after an audit report found he had broken procurement rules.

Silence is neither fear nor shame. Silence is respect and wisdom, till the opportune moment

The audit report, parts of which have been seen by this newspaper, found that Mr Bundy had unilaterally entered into a €500,000 car-lease deal and had “consistently bullied” the senior management.

Conducted by local auditors RSM, the report mainly focused on an eight-year procurement deal which Mr Bundy made with Burmarrad Commercials.

The lease deal, for 14 vehicles, included Mr Bundy’s own car.

The audit was ordered after the PBS board last month informed the government it had lost confidence in Mr Bundy.

Sources said the audit also highlighted concerns about salary increases and promotions that Mr Bundy gave.

RSM was alerted to the unilateral promotion decisions by members of the company’s management who had themselves been given increases.

On Sunday, Mr Bundy took to his personal Facebook account saying he would not be silent for long.

“Silence is neither fear nor shame. Silence is respect and wisdom, till the opportune moment,” he wrote.

Last week, Mr Bundy wrote a post accusing PBS chairman Tonio Portughese and “his clique” of wanting to get rid of him.
