With just weeks to go, the Maltese Island swim in aid of UK licensing industry charity The Light Fund has found itself two members down.
Jessica Johnson, who was swimming on behalf of PR agency Kilogrammedia, has broken her leg and so will not be able to take part.
What's more, work commitments of Kilogrammedia's other sponsored swimmer, lawyer Henry Mitchell - who now has a date with the Crown Court - means that he has also pulled out.
With the places paid for, two new volunteers are urgently being sought (the cost of flights would still need to be covered).
Swim organiser, Stephen Gould, co MD at 4Kids, explained: "It's a huge shame that we have lost swimmers at this stage, however, with the majority of their costs having been covered by Kilogrammedia it does offer an excellent opportunity for two more volunteers to join us at very little expense to themselves."
