Whilst not technically 'full sponsorship', the NetJets scheme is still open until Sunday if you have not already looked at it.

Whilst you do have fund the training yourself, there is an enhanced loan arrangement with HSBC to loan up to 60k. More importantly, along with the relative security of a conditional job offer, UK residents get their training costs reimbursed from their Gross rather than Net salary so that is almost equivalent to a 40% subsidy by Gordon Brown.
Also, you don't have to pay for the type-rating.
