The company confirmed Duncan Weldon started at the firm on Monday to strengthen the asset allocation research team through sharing views on market strategy, idea generation and investment research.
Weldon has spent time at the Bank of England, as head of research at the Resolution Group and as a partner at Senhouse Capital.
He was also appointed BBC Newsnight’s economics correspondent in 2014 and was economics adviser to the leader of the opposition, Harriet Harman, in 2010, as well as a senior economist at the Trades Union Congress.
Weldon’s appointment at the BBC was met at the time with uproar from certain Conservative MPs, including Andrew Bridgen, because of his Labour Party affiliation and his perceived lack of journalistic experience.
LGIM head of asset allocation Emiel van den Heiligenberg said: “We are delighted Duncan is joining the asset allocation team and look forward to leveraging his experience and insight in our investment research and allocation decisions. The expansion of the team is testament to growing client interest and strong performance of funds across our multi-asset range.”
