The crisis at FTSE 100-listed healthcare operator NMC Health looked set to draw in forex payments group Finablr, with which it has large shareholders in common. Finablr warned of a cashflow crunch and said it would commission an independent review of its finances.

Finablr, which owns UK foreign-exchange group Travelex, said in a market statement this morning it was “taking urgent steps to assess accurately its current liquidity and cashflow position”. The announcement sent its shares plunging, down 66% to 7.7p as of 14:30pm GMT, on a day when the broader FTSE 250 index had lost 9.7% by that point.
