UK's FTSE 100 hit its highest level in more than five weeks on Tuesday as commodity stocks rallied on the back of a weaker dollar ahead of a key U.S. Federal Reserve verdict, while BP was volatile despite the oil giant topping third-quarter estimates.

The blue-chip FTSE 100 jumped 1.5% by 0817 GMT, while the domestically oriented FTSE 250 rose 1.3%.

Shares of BP hit February 2020 highs and pared early gains to trade up 0.6%. The oil giant said it had more than doubled its quarterly profit to $8.15 billion year-on-year amid calls to increase taxes on the energy sector.

The UK's energy sector climbed 1.6%, while mining sub-index rose 3.9%, tracking stronger commodity prices that were buoyed by a weaker U.S. dollar.

Ocado Group jumped 22% after the British online supermarket group said it has entered the South Korean market through a partnership deal with Lotte Shopping.

Market focus was on the U.S. and UK policy decisions slated for Wednesday and Thursday, respectively, where both central banks are expected to raise interest rates by 75 basis points each.

British house prices in October recorded their first monthly fall since July 2021, declining 0.9% after being flat in September, as the market was hit by turmoil during Prime Minister Liz Truss's short-lived premiership. (Reporting by Anisha Sircar in Bengaluru; Editing by Sherry Jacob-Phillips)
