THE HOUSE of Commons is beefing up its security to prevent a repeat of the attack which saw Prime Minister Tony Blair showered in purple powder last year.
Two members of pressure group Fathers 4 Justice threw the powder into the chamber of the House last May, halfway through prime minister's questions.
The incident occurred despite a £600,000 security screen having been erected just weeks before. But the front three rows of the gallery - usually occupied by peers and distinguished guests - is outside the screen.This is where the two men staged their protest.
Now building bosses at the Houses of Parliament have moved to plug the gap.
Surrey glazing specialist Portal is due to move on site to fit in the additional glass when Parliament goes on its summer recess next month.
The £400,000 deal, which is being carried out for on-site builder GE Wallis, will be completed by the time Parliament returns on October 10.
