The portcullis stays. It's there for a reason.

There is a wailing noise being emitted by an ignorant minion of the undignified dwarf who insists on perching upon the Chair of the Speaker of the House of Commons.

The minion opines that the portcullis symbol of the Parliament of the United Kingdom of Great Britain and Northern Ireland is offensive and should be abolished, being an anachronistic sign of exclusion in this age of inclusivity.

Damn right. 

Leaving aside the fact that too many utter bastards are 'included' in this nation and its affairs, to the extent that said bastards are no longer merely included but increasingly deferred to and thereby stealthily gaining ascendancy over the native citizenry, we may reflect on the original defensive purpose of the portcullis and in particular its abiding and important meaning in the Parliamentary context.

The portcullis is there to remind prince and pauper, native and alien, that the Parliament of the British people may not be entered, attacked or suborned by any person or persons whatsoever.

It symbolises the determination of the people of the United Kingdom to guard their Parliament, with force if necessary, against all threats from whomsoever — including seditious fifth-columnist public servants who would do better to keep their modish opinions to themselves and their fucking mouths shut.
