Two MPs and one lord have taken up new lobbying or advisory roles connected with law firms over the past year, parliamentary registers show.

New on the register is John Hutton, Labour MP for Barrow and Furness, who was paid £11,000 by national firm Eversheds to speak at a series of private dinners over six days.

Keith Vaz, Labour MP for Leicester East, is now paid £2,500 a month as a consultant to Indian firm Fox Mandal Little ‘on legal matters and especially on the Asian diaspora in the UK and abroad’.

Lord Jones of Cheltenham has a parliamentary consultancy agreement with Oxford firm Crossland, which pays £833 a month. He was previously employed by London and Reading firm Doyle Clayton as a non-parliamentary, non-executive adviser.

Also new on the register, although not connected with lobbying or advisory work, are Rob Marris, MP for Wolverhampton South West, who receives an annual donation to his constituency Labour party from national firm Thompsons; and Theresa Villiers, Conservative MP for Chipping Barnet, who received ‘one-off pro bono legal advice’ from magic circle firm Clifford Chance in April 2009.

MPs and lords do not break any rules by advising or working for law firms, or advising clients through their firms’ lobbying practices. However, earlier this month, Conservative leader David Cameron warned that his party will shine ‘the light of transparency’ on ‘corporate lobbying’ if the Tories take power at the forthcoming general election, indicating that such arrangements could come under greater scrutiny.

In all, 12 lords and six MPs are listed as having either parliamentary consultancy, parliamentary lobbying, or non-parliamentary advisory roles with law firms.

A number of lords and MPs undertake occasional legal work as solicitors, barristers or judges.
