The House of Commons technically retains the power to impeach Ministers of the Crown (or any other subject, even if not a public officer) for their crimes. Impeachments are tried by the House of Lords, where a simple majority is necessary to convict. This power has fallen into disuse, however; the House of Commons exercises its checks on the government through other means, such as no confidence motions; the last impeachment was that of Henry Dundas, 1st Viscount Melville in 1806.
