Personally I prefer my politicians to be chosen from the ranks of those who ask and answer questions (awkward and otherwise); from those who inquire, who have open minds and who tend to actually think (coherent) thoughts. Not to mention ones that tend not to come from parties that have been in receipt of donations from Russian and Serb businesspersons or are very happy in the company of filthy rich oligarchs.
Teresa May's conduct as Home Secretary deserves scrutiny as the failure to hold an inquest into the death of Alexander Litvinenko - there were a number of suspicious deaths amongst the Russian emigre community (and associates) during a certain person's tenure as Home Secretary. The decision not to investigate because it may have been prejudicial to business / city interests remains questionable to say the least.
The Brit (and City) elite are too comfortable not asking questions (let alone answering them) particularly those related to where the cash has come from. This is something that has been noted by the House of Commons Foreign Affairs committee has reported that London was being used to hide the "corrupt assets" of President Vladimir Putin and his allies. It's also been noted that despite the poisoning of Russian ex-spy Sergei Skripal and his daughter it remains "business as usual" for the City.
