The House of Lords should be abolished after Brexit, a Scottish Tory think tank has argued.

In a new report the Bright Blue Scotland group says the Lords should be scrapped and replaced with a senate, with representatives from across the four UK nations.

Conservative MSP, Murdo Fraser, wrote the report, and said change is needed to help keep the UK together in the face of independence movements in Scotland, Wales and nationalists in Northern Ireland.

The idea is for a quasi-federal state with an upper chamber, mostly or entirely elected, to scrutinise and revise legislation from the House of Commons.

Mr Fraser, said: “Introducing a UK-wide Senate delivers the long-awaited and overdue reform of the House of Lords, giving a better balance to the UK constitution and protecting the interests of the nations and regions furthest from London.

"A new quasi-federal settlement can mitigate concerns that exist in Scotland, Wales and Northern Ireland, and also are growing in many parts of England, about an over-centralised state where, despite asymmetric devolution over a period of two decades, there is still pressure for more power to be passed down from the centre."

There are currently around 783 members of the House of Lords, including 92 hereditary peers and 26 Church of England Bishops and the rest appointed by an appointments commission for non-political Lords, political parties and the Prime Minister, including many former elected MPs and Cabinet ministers.

The SNP does not send any representatives to the House of Lords and wants it abolished.

Ryan Shorthouse, director of Bright Blue, said: "Our departure from the EU provides the impetus to introduce important governmental and constitutional reforms to create a 'quasi-federal' future for the four nations of the union.

"Notwithstanding the difficulties and divisions Brexit has created, it does offer an opportunity for overdue democratisation and modernisation of key institutions of the union."
