• On Monday, the Guardian, the BBC, Le Monde and 50 other media outlets reveal that HSBC’s Swiss banking arm helped wealthy customers dodge taxes and conceal millions of dollars of assets, doling out bundles of untraceable cash and advising clients on how to circumvent domestic tax authorities. The HSBC files consist of thousands of pages made available via the International Consortium of Investigative Journalists. Covering the period 2005-07, they amount to the biggest banking leak in history, shedding light on some 30,000 accounts holding almost $120bn (£78bn) of assets. Many of the accounts belonged to prominent figures in business, film, music and sport, and the heads of royal families.

France, Belgium, Spain, the US and Argentina have launched legal proceedings against HSBC and its high net worth clients. So far, £135m has been recovered from HSBC clients in the UK. France has recovered £188m in taxes and fines from a list of 3,000 clients and Spain has recovered £220m, also from 3,000 clients. Australia said it had recovered more than A$30m (£15m) over the past five years.  Key article: HMRC had data on misconduct before bank boss made trade minister  • HMRC failed to warn that there was serious evidence of misconduct at HSBC’s Swiss arm despite being asked to vet Green over his suitability to become minister. HMRC had received a disc in 2010 with 6,000 names “all ripe for investigation” David Hartnett, told MPs on the Treasury select committee in 2011. Then head of tax at HMRC, Hartnett went on to work for HSBC as a consultant after his retirement two years after the data was handed over.

Their ranks include Zac Goldsmith, MP for Richmond Park, plus his brother the financier Ben Goldsmith, and a Swiss resident, the German-born car company heir Georg von Opel, who has donated six-figure sums in the past two years.

The finance minister, Cristóbal Montoro, has asked for a “study of the legal actions that can be taken against HSBC” over the 2,694 Spaniards holding accounts in the Swiss subsidiary, with savings of $2.3bn (£1.5bn). Barack Obama’s attorney general nominee, Loretta Lynch, said the bank could face tax-evasion charges if there were sufficient evidence, despite a settlement she reached with HSBC two years ago over money-laundering with Mexican drug cartels and breaches of US sanctions. In Belgium, a judge was already considering issuing international arrest warrants for directors of HSBC over tax fraud allegations. In Denmark, the government said it would seek the names of its citizens who may have used Swiss bank accounts to avoid domestic taxes.
