Spread betting and CFD provider London Capital Group (LCG) has lost another member of its senior management team with the departure of group finance director Siobhan Moynihan.

Moynihan has decided to seek a new challenge after three years with the company, and will be leaving towards the end of this year.

She joined LCG in 2009 as financial controller, having previously worked at Deloitte for nine years. She was appointed group finance director in 2010.

“I would like to thank her for her dedication and hard work over the past few years and we will appoint her successor in due course,” said LCG chairman Giles Vardey this morning, alongside the company’s interim results for the first half of 2013,

She becomes the latest member of LCG’s senior management team to leave the company, following a string of departures this year.

Chairman Richard Davey was the first to leave last August followed by LCG’s chief operating officer Rachel Woodford who announced her departure in January of this year (although she didn’t leave the company until July).

She was followed by long-term CEO Simon Denham who stepped down in February.

Denham was replaced by former Marex Financial CEO Mark Slade, who later resigned for personal reasons after less than six months in the role. He was replaced in July by Kevin Ashby, who had joined LCG in May as chief commercial officer.
