Two roses are set to be placed on the Commons benches where Jo Cox used to sit, Labour MPs have said.
The flowers, one white to mark her Yorkshire roots and one red in Labour's colours, are in memory of the mother-of-two who was murdered last week.
It was being left on the green leather benches as Parliament was recalled to pay tribute to their late colleague, who was shot and stabbed in her constituency last week.
A solitary prayer card reserved her seat earlier today, as the Home Secretary met with senior Commons and police officials to discuss how to improve security in the wake of the shocking killing of the 41-year-old MP.
Labour MPs, particularly her friends from the 2015 general election intake, were expected to wear white roses in their buttonholes.
The party is set to sit together as a group in a show of solidarity, although some Tory MPs such as Ms Cox’s neighbour Jason McCartney and others may ‘cross the floor’ in a symbolic show of cross-party grief.
Following the hour-long tributes, MPs will head to St Margaret’s Church opposite Westminster, for a memorial service. A simultaneous tribute will be held in the House of Lords.
