Just what does that mean?

Lord Pearson of Rannoch asked HMG in a Written Question:

To ask Her Majesty's Government, further to the Written Answer by Lord McNally on 15 November (WA 140), whether the Deputy Prime Minister, Mr Nick Clegg, is eligible to receive a pension from the European Commission; if so, when that pension will become payable; what will be its annual amount; and whether the terms of that pension constrain his actions.

HMG's response was a little odd:

The Deputy Prime Minister is no longer eligible to receive a pension from the European Commission.

No longer? What does that mean? Was he at any time and why is he not so any longer?
