A right royal cheek

Former Prime Minister, Lady Thatcher, has upset the College of Arms with her letterhead, said to breach heraldry laws. The logo, with the name Margaret Thatcher and a version of the Queen’s coat of arms, is said to be presumptuous. Only the Queen should use the symbol, say experts. Is the former PM following in the footsteps of packaging copycats and trying to pass herself off as royalty?
