During Mr Grayling's statement earlier, a number of Conservative MPs pressed for more details about the laptop cabin ban and expressed concerns about the political signal that it sent out.
Former Foreign Office minister Huge Swire, who has just returned from a trip to Egypt, said he had seen first hand the "devastating" impact that the ban on flights to Sharm-al-Sheikh and said many in the country felt that they were being "singled out".
He said British ministers and officials needed to go on a "diplomatic offensive" to explain why the measures were necessary.
Sir Desmond Swayne, a former international development minister, had a very succinct question, asking Mr Grayling why ministers believed laptops, tablets and larger mobile phones were "safer in the hold".
The transport secretary said he could not discuss the detail of the evolving security threat but the UK had taken the right decision in terms of protecting British citizens.
In response, Sir Desmond was seen to nod his head rather ruefully and sport what can only be described as a quizzical look.

The bill has cleared all stages in the House of Lords.

He goes on to say that the UK must make its own security arrangements, and that measures taken by the United States "is a matter for them".
Mr Grayling says he will be writing to UK insurers to make them aware that insurance will be required to cover electronic devices carried in hold luggage where the risk of theft is greater.
