Sam Larke points me in the direction of the latest update to the official Konectbus fleetlist where two further withdrawals have been made.
Optare M920 Solos 900 VX51RHZ and 901 VX51RJZ are both withdrawn from service at Konectbus. The latter is currently on loan to sister company Anglianbus. Both of these buses had been new to Konectbus in the first half of 2002.
On another note, I am reliably informed that Mercedes Benz Citaros artics 801 BD57WCY and 803 BL57OXM, which were withdrawn in September, have been sold and await collection. 804 BL57OXN is currently being used as a source of spare parts.
