"Boris is the best liar we have ever had as Prime Minister, and has successfully perpetuated the notion that all politicians lie, and so he is no worse than the next one.
'This canard has been unforgivable. My father, Woodrow Wyatt, was a politician for forty years and Margaret Thatcher and members of her Cabinet were frequent guests at our home.
'They did not lie their heads off, though sometimes obfuscation is a necessary part of a politician's armory. Thatcher, who had unimpeachable probity, would be horrified by Boris, not only the man, but his determination to cling inelegantly to office to the detriment of the country.'
