THE SNP have called for a public inquiry into “cash-for-honours”.

The call comes after the Prime Minister raised 36 people, including some of his party’s biggest donors, to the House of Lords.

Among them was millionaire Michael Spencer who has donated some £6 million to the party’s coffers.

As well as the big-money donors, those granted a cushy job for life included former Scottish Tory chief Ruth Davidson, Johnson’s brother, Jo, former cricketer Ian Botham and Russian-born newspaper owner Evgeny Lebedev.

Along with the Labour and non-affiliated peers, the total number of un-elected peers is now to close to 800.

Analysis by the Financial Times, published last week, said of the 308 peers created over the last 13 years, 15 were Tory donors, three were Labour benefactors and four were LibDems.

The majority of the cash came from the Tory-backing businessmen, including £3.5m from Stanley Fink, £8.2m from Anthony Bamford, £8.6m from Michael Farmer, £3.3m from James Lupton, £3.4m from Alexander Fraser and £2m from David Brownlow.

Darren Hughes, chief executive of the Electoral Reform Society, said: “Pressure is mounting for an overhaul of the Lords, after this shocking batch of cronyistic appointments.

“Even the Lord Speaker recognises that this situation is untenable and has completely over-ridden even the Lords’ modest attempts at self-regulation.

“At over 800 members, this bloated chamber is making a mockery of democracy.”

A Tory party spokesperson told the FT: “Party donations do not play any part in the selection process. It is wrong to criticise individuals being honoured just because they have also chosen to donate to a political party.

“Donations should be transparent, but that is not an excuse to knock people for broader philanthropy, enterprise and public service.”

The SNP’s Pete Wishart said: “The House of Lords is utterly undemocratic and should have been abolished decades ago – but the Westminster parties have clung on to it and used it to reward their donors and cronies.

“It might just be an amazing coincidence that so many major donors to the Tories, Labour and Liberal Democrats have all been given peerages but many will conclude that the system stinks.

“It’s time for a fresh ‘cash-for-honours’ public inquiry to determine the role that political donations are playing in the Westminster establishment and appointments to the Lords.

“The Westminster system is rotten to its core. It is ridiculous that Tory and Labour leaders have been able to hand out peerages like sweeties to their friends, family, and donors like a banana republic. In any other country that would rightly be considered corrupt.

“If Baroness-in-waiting Ruth Davidson had any integrity she would hand her own peerage back and refuse to sit in this archaic swamp of Brexit cranks, donors and apparatchiks.”

Meanwhile, the ERS said the new batch of Lords only added to the upper chamber’s lack of regional representation. Their analysis found that nearly a quarter of peers are based in London compared to just 13% of the UK public.

Over half – 55% of peers – live in the capital, or the East and South East of England.
