I have been asked to reply and will answer this question shortly.
Substantive answer from Dr. Ladyman to Nigel Evans:
The European Union (EU) and member states of the European Space Agency (ESA) jointly fund the design and development programme for Galileo. To date the UK's subscription to the ESA element of the programme has been €142 million.
The EU's contribution to the design and development programme is made from the EC budget and is estimated by the Commission to be €790 million. The UK's contribution to the EC budget is around 17 per cent. of the total, before the UK receives any abatement. The United Kingdom makes its contributions to the EC Budget as a whole and not to individual spending programmes within it. There is not an identified United Kingdom contribution to the design and development programme via the EU budget.
