The FTSE 100 is up by around 15 points so far today in a quiet day for London’s biggest listed firms.

WPP (+6.03%) is the biggest riser so far, having reportedly won the UK Government’s £1.5bn strategy, planning and buying business ahead of Omnicom.

Defence companies on the prestigious index are also on the up, with Babcock (+2.47%) and BAE Systems (+2.07%) both experiencing price rises.

North East-based tech firm Sage (+2.48%) and education giant Pearson (+1.72%) are other incremental gainers making up the top five.

Meanwhile, Tesco (-1.73%) has dropped as it faces pressure from competitors as we enter the festive period.

The biggest loser so far today is Antofagasta (-3.01%) but the company is up by over 5% over the course of the last month. Easyjet (-1.49%) has also very slightly lost ground.

In the FTSE 250, Trustpilot (+5.38%) is the biggest riser. This follows a multitude of “transaction in own shares” RNS announcements and could be related to an ongoing buyback programme.

Helios Towers (+4.53%), Playtech (+3.15%), Man Group (+3.08%) and Close Brothers (+3.00%) round out the top five gainers.

On the flip side Ceres Power (-3.93%), Chemring (-3.64%), PayPoint (-3.91%), Wizz Air (-3.00%) and Partners Group PEY (-2.40%) has dropped slightly so far in what has been a day of not much movement in London.
