Liechtenstein has entered into a bilateral agreement with Luxembourg, making it the third it has signed since March. The agreement follows on from those it signed with the US and Germany. Liechtenstein has come under scrutiny in recent months as governments are beginning to crack down on banking secrecy and tax havens. Its agreement with Luxembourg will see the two small countries exchange data to help whittle out tax cheats, the Telegraph reports. The movement for compliance with the Organisation for Economic Cooperation and Development got more urgent in March at the G-20 summit in London. A tax-sharing agreement has also been signed between Britain and Liechtenstein.
