US drug firm Pfizer has claimed its commitments to preserving British jobs if it takes over AstraZeneca are legally binding.
A statement to politicians ahead of a May 13 panel meeting, the firm announced:
To ensure our commitments are binding, we included them with our proposed offer announcement understanding fully that they would be binding as a matter of English law.
Pfizer has given a five-year commitment to complete AstraZeneca's new research centre in Cambridge, retain a factory in Macclesfield and put a fifth of its research staff in the UK if a deal is agreed.
But the firm has also said it could adjust those promises if circumstances change "significantly".
