More than 50 MPs have owned stakes in publicly listed companies that raise questions about possible conflicts of interest and that until now have been in effect secret, the Guardian can reveal.
Parliamentary rules mean MPs’ shareholdings, including ones that were held by the former prime minister Theresa May and the former education secretary Gavin Williamson, do not need to be publicly disclosed in parliamentary registers. But as a result voters are left in the dark about some of the financial interests of their elected representatives.
