I personally have had enough of the unelected liberals in the upper house. We only have one elected entity in the UK and its the house of Parliament. Not the government, not the PM, nor the house of Lords nor the head of state.
Its all a historical anacronysm.
Instead we could have a 5 yearly elected upper house. Eligible candidates could be those with a Knighthood for public service or similar. We could have 300 or 400 full time Lords elected via regional list. The largest coalition could form the senior leadership and the lead of the house could be formal head of state.
The Windsors can lose all formal power and access to public funds and assets.
