> was up 29.75 points at 4,377.86 points in choppy trade having been down as low as 4,307.72 points earlier."The banks have taken the initiative this morning. They have been sold off over the past two weeks and recovering some of that ground this morning," said Rob Griffiths, equity strategist at Cazenove.
"We have just come from the reporting season so it is not clear what is going to drive the market this week... it will be interesting to see if we can hang on to the current level or will give up ground like last week," he said.
Bank stocks added the most points to the index with Lloyds Banking Group <LLOY.L> up 1.6 percent. Victor Blank is to step down as chairman of the group in the next year, following intense criticism of the part-nationalised British bank's purchase of troubled rival HBOS. [

Thomas Cook Group <TCG.L> gained 11.4 percent. Debt-burdened German retailer Arcandor <AROG.DE>, which has a controlling stake in Thomas Cook, plans to ask the German government for 650 million euros ($885 million) in loan guarantees and a loan from the German state development bank. [
]"The end of last week saw it (Thomas Cook) report revenues up around 12 percent for the first six months, suggesting it has weathered the storm much better than many were expecting for the travel sector," said David Jones, chief market strategist at IG Index.
"Since November last year, the share price has risen by around 80 percent and at the moment some traders seem to be banking on this recovery continuing and eyeing a run back to the highs for this year, just above 300 pence," he said.
ENERGY STOCKS RISE
Energy stocks rebounded from earlier losses as oil <CLc1> rose to over $57 a barrel.
Royal Dutch Shell <RDSa.L> recovered from earlier falls to gain 0.3 percent.

Cairn Energy <CNE.L>, which has significant exposure in India was up 3.1 percent, while miner Vedanta Resources <VED.L> gained 2.4 percent, as the Indian company was bolstered by the decisive victory for the ruling coalition in that country, calming fears of political instability.
Otherwise mining stocks took the most points off the index as copper <MCU3=LX> fell 1.1 percent, with Rio Tinto <RIO.L> down 4.5 percent.
An executive at the global miner said roughly half of China's iron ore mines may have shut down since prices for that commodity dropped, opening the door for other low-cost producers to supply China with the key mineral for making building materials. [
