He told MPs:
"We owe a huge debt to those who serve in our armed forces. They will always be welcome in this place… I'm glad to say
that we will ensure that up to six visiting serving members of the
armed forces will always be found a place in the gallery whatever the
other pressures may be."
And if more than six service personnel are visiting at the same time, the Guardian's Andrew Sparrow reports that "those who cannot get seats in the Commons gallery will be given a tour
of the Palace of Westminster and the opportunity to sit in the public
gallery in the House of Lords until a seat in the Commons gallery
Update: Paul Waugh adds that Tory MP Philip Hollobone has asked the Speaker to consider using the little-used Members' Gallery for this purpose.
