High Street bellwether Marks & Spencer (MKS) is marked down 1.8% to 436.2p as investors fret ahead of Thursday's (9 Jan) third quarter trading statement covering the crucial Christmas period. The Sunday Times claims festive trading was dismal, with deep discounts failing to arrest sliding sales with clothing and homewares revenues reversing up to 1.5% to heap further pressure on chief executive officer Marc Bolland.

Troubled insurer RSA (RSA) improves 5.7% to 97.4p ahead of the results of an investigation into its Irish business on Thursday. The group issued three profit warnings and the CEO quit in late 2013 following concerns over the high level of injury claims in its motor business.

Investors seem unimpressed with Clear Leisure's (CLP:AIM) plans to build up a restaurant business that it can potentially spin off as a separately-listed entity in time. The shares are flat at 2.1p as it buys 51% of Lasagnette, a restaurant concept that has the rights to use the images of cartoon character Garfield, a well-known lasagne fan. Clear Leisure's food offering is minimal at present with merely an Italian sushi business.


Recruitment agency Staffline (STAF:AIM) rises 2.6% on a robust trading update to 565p. The running Shares Play of the Week will report full-year results on 29 January.

Staffline specialises in blue-collar workers.


Meat retailer Crawshaw (CRAW:AIM) racks up a near-15% gain at 19.38p on a tasty Christmas trading update.

Shares flagged the Rotherham-headquartered counter as a momentum trade in October.

Sports marketing services specialist Chime Communications (CHW) fails to respond to an upgrade from Canaccord Genuity.

Self-storage concern Lok’nStore (LOK:AIM) improves 1% to 198.5p after buying a new site in Bristol.
