(Sharecast News) - London stocks were set to rise at the open on Thursday following a positive session on Wall Street, as investors eyed the latest policy announcement from the European Central Bank.

The FTSE 100 was called to open around 25 points higher.

Ipek Ozkardeskaya, senior analyst at Swissquote Bank, said: "The market's reaction to ECB decision and the post-decision presser could be mixed. A rate cut today, a dovish message from the ECB and another 25bp cut in December are already widely priced in.

"Lagarde's tone at the post-decision press conference will play a crucial role in determining whether the euro will further weaken against the dollar. We could see a buy-the-rumour-sell-the-fact reaction to today's decision if Lagarde highlights risks regarding the softening inflation."

The ECB rate announcement is due at 1315 BST.
