Head of lobbying firm Blakeney says industry concerned about perceived lack of transparency and trust

• One in 10 peers paid for political advice

The leader of the House of Lords has been urged to back calls for tighter restrictions on peers being paid to offer political advice after a Guardian investigation found one in 10 have held such roles.

Gabe Winn, chief executive of Blakeney, a lobbying firm, wrote to Angela Smith on Tuesday, saying he and many others in the industry believed the issue was “bringing the work of the House of Lords into disrepute”.
