Over 70 swimmers took a dip in the chilly St Julians sea for a good cause yesterday. The charity swim, which started off as a challenge about 10 years ago by Anton Buttigieg, a manager at Thomas Smith Group, has since become an annual charity event supported by the company. As a result of yesterday's swim, over €2,000 will be donated to Ir-Razzett tal-Ħbiberija but the promoters are hoping more money will trickle in.
