Private companies will be forced to publish details of the pay of executives to stop "irresponsible" and "careless" behaviour in the wake of the BHS scandal under plans announced by Theresa May .

The Prime Minister will say that she wants to ensure that "everybody plays by the same rules" as she unveils plans to make firms publish "pay ratios" revealing how much more executives get than average workers.

She will also say that she wants to bolster the role of pension trustees to give workers and retirees more of a "voice" in the future of the companies which hold their life savings.

Ministers will consider plans to increase the proportion of pension trustees who are nominated by workers and give them more power to halt takeovers if there are concerns about the suitability of investors.
