LONDON, May 16 (Reuters) - The new chief executive of Britain's BT Group on Thursday set out a path to more than double free cash flow over the next five years as the telecoms group passes the peak of its investment in fibre networks.

Allison Kirkby, who previously led Sweden's Telia, said BT would increase its dividend for the 2024 financial year by 3.9% to 8 pence a share after free cash flow beat expectations.
