 Carillion operated 13 UK pension schemes, with around 27,000 members, of whom over 12,000 already received pensions.Despite initial estimates of a £587m deficit, reports suggested the true figure could be between £800m and £2.6bn; on 29 January 2018, Frank Field, chair of the Work and Pensions Select Committee accused Carillion of trying to "wriggle out" of pension payments, resulting in a £990m deficit.Pensions advisers were said to have repeatedly warned that Carillion was prioritising shareholder dividends over the funding of its pension scheme.
