Morgan was censured by the Press Complaints Commission and one of the column's writers, James Hipwell, was jailed for share ramping, while his colleague Anil Bhoyrul was given a community service order.
There is no suggestion of any deliberate wrongdoing on the part of Collins, nor that he made any financial gains as a result of his breaching Reuters' regulations. It was, in fact, Collins who brought his dealings to the attention of his bosses.
Collins, a prominent and vocal critic of the Financial Services Authority, has made no secret of his interest in share dealing in the past.
While at the Telegraph he made clear to its financial journalists that the paper could hardly encourage readers to invest and save for their retirement if it then barred journalists from so doing by owning shares.
However, the affair still comes at a difficult time, with tensions running high between the financial media and the Financial Services Authority. The FSA recently warned all regulated firms that any 'first inquiry' from a journalist to members of their staff should be immediately referred to the company's media relations team.
The watchdog said the aim was to clamp down on leaks of price-sensitive information, but senior journalists have accused the FSA of being involved in censorship, and warned that its action could stifle legitimate journalistic inquiry and prevent effective communication between the media and the City.
The FSA has recently begun a crackdown on 'market abuse' and has taken an aggressive stance against City miscreants seen as breaching rules by using their inside knowledge of deals to reap financial rewards. The crackdown has led to dawn raids on individuals and banks.
Neither the FSA nor Thomson Reuters was prepared to comment on whether the watchdog had been contacted by Reuters about the Collins affair, or whether it would be investigating.
In an email to Dixon, the editor of Reuters Breakingviews, Collins admitted that he had committed a 'serious but technical' breach of the rules.
The Reuters investigation into share dealing by its staff is 'continuing', according to the editor-in-chief, David Schlesinger. He has urged staff to look carefully at their own market participation to ensure that they comply with its rules.

This article has been changed from an earlier version.
In a syndicated article published by us on October 19, 2010 and which has continued to be published on the internet, we alleged that Margaret Doyle, a senior financial journalist at Thomson Reuters had been investigated and found to have breached strict guidelines set by her employer, Thomson Reuters.
This was untrue. Ms Doyle has not fallen foul of any guidelines that have been laid by Thomson Reuters or any financial regulator.
We apologise to Ms Doyle for any embarrassment caused.
