According to a report from jobs firm Debut, the miner and the Betfair owner have only 20% and 21% of women as top executives, respectively.
Drinks manufacturer Diageo PLC (LON:DGE) dominated its peers with 63% female representation, followed by retailer Auto Trader Group PLC (LON:AUTO), estate agent Rightmove PLC (LON:RMV), utility firm Severn Trent PLC (LON:SVT) and housebuilder Taylor Wimpey PLC (LON:TW.) with 56%.
Across the whole index, women are taking 36% of current board roles, with just five currently employing more female directors than male.
However, just nine out of 100 companies have achieved and almost a third of companies are yet to meet the 33% target set by the government.
Back in 2015, Westminster set up the goal of all FTSE 350 boards having 33% female representation by 2020, which would bring to 350 more women in top positions.
The recommendation came after FTSE 100 reached a milestone of 25% of board positions being filled by women set four years prior.
