Researchers and campaigners welcomed a new report issued on 29 March by UK parliamentarians which argues that the British government is failing to fulfil its international obligations against bribery, corruption and money laundering; and highlights the role of UK-linked tax havens in laundering the proceeds of African corruption. The report, launched in London by the All Party Parliamentary Group on Africa, argues that the UK is not doing enough to tackle the 'supply side' of corruption: limited financial transparency and weak corporate regulations which allow UK multinational companies to be involved in corruption, and for allowing dirty money to be channeled through British banks, shell companies, trusts and financial professionals.
