Jackson supporters reject demand for inquiry over ballot-rigging allegations

Right-wing leaders of one of Britain's biggest unions rejected demands last night for an inquiry into alleged ballot-rigging by the general secretary, Sir Ken Jackson.

Sir Ken, one of the Prime Minister's closest union allies, yesterday denied claims that he had participated in a scam to try to ensure his re-election. His supporters on the executive of Amicus-AEEU are resisting calls for an inquiry.

Derek Simpson, a left-winger who defeated Sir Ken and will become general secretary in January, said the accusations had cast a "dark shadow" over the union. He said: "The allegations have caused me grave concern and members have contacted me expressing their dismay at the way these claims reflect on our union. Justice must be seen to be done and the executive should undertake an immediate and thorough investigation so that the full facts can be presented to the membership.

"There will be a full investigation when I take office in January, but it would be better if it took place before then."

Roger Maskell, former secretary of the union in London and the South-east, has accused Sir Ken of presiding at a meeting during which it was suggested that employees of the union vote more than once to nominate the incumbent.

Mr Maskell, who has admitted his own involvement in ballot rigging, also alleged that Sir Ken was present when it was suggested that he should be nominated by branches even though they had not met to discuss the issue.

Sir Ken denied the claims and said he would be presenting evidence to support his assertion at an employment tribunal in November where Mr Maskell is claiming unfair dismissal from the union.

He argued that Mr Maskell resigned after admitting his involvement in malpractice but the former official claims that he was in effect sacked.

Sir Ken said: "I was not involved in any wrongdoing. I had no knowledge and what's more important is I can provide evidence that I had no knowledge and no involvement."

Referring to Mr Maskell, Sir Ken said: "He did accept he committed the offences I have been accused of. He accepted that and he resigned.''

Sir Ken said the union's executive – dominated by his supporters – saw no point in ordering an inquiry because no evidence had been presented to them. Asked why he did not deny the allegations of malpractice on Sunday, when they were put to one of his aides, he said his union's solicitor had not been contactable.
