LONDON (MarketWatch) -- The U.K.'s benchmark index dropped sharply Tuesday after mining and financial stocks came under pressure, as speculation escalated as to whether Ireland will accept a bailout.

A handful of mid-cap shares, however, posted gains after well-received trading updates.

The FTSE 100 index fell 1.7% to 5,722.56 in afternoon trading. Worries over a potential interest-rate hike in China weighed on commodity prices and mining stocks.

Xstrata PLC dropped 3.8%, Rio Tinto PLC (RIO) declined 3.7% and Kazakhmys fell 5.2% as all the mining stocks in the benchmark index traded in the red Tuesday.

Bank stocks also weighed on the FTSE as uncertainty over a potential bailout of Ireland continued to concern investors.

Shares in Lloyds Banking Group PLC (LYG) slumped 3.6% and Barclays PLC (BCS) dropped 2.6%.

Several companies reporting earnings and trading updates had a better session. House builder Taylor Wimpey PLC rose 2% after it said profit would be towards the top end of its expectations and added that it has agreed the terms of a new credit facility with a group of lenders.

While the company didn't release details of the new borrowing facility, Deutsche Bank analyst Glynis Johnson said the interest rate the group is paying is likely to have fallen significantly to around 8% from 11%.

The results "have reinforced our view of strong margin improvement to 2013 driven by the substantial land write-downs and cost savings," Johnson said.

Shares in rival Persimmon gained 0.8%.

TalkTalk Telecom Group PLC was another mid-cap riser, adding 4.8% after reiterating its guidance and saying it's targeting a 20% margin over the medium term.

Jefferies International analyst Jerry Dellis said the margin guidance is significantly better than the 16% consensus forecast and was the "key positive" factor in the results.

He said the guidance suggests there is around 25% upside to the consensus forecast for earnings before interest, taxes, depreciation and amortization in three to four years.

On the downside, shares in Punch Taverns PLC dropped 7.9% after the firm said its Finance Director Phil Dutton will leave the company next year.

Low-cost airline easyJet PLC dropped 4.1% even after saying pretax profit for the year jumped to 154 million pounds ($247 million) from  £54.7 million and that it expanded its fleet by 24 aircraft, which will give it a total of around 220 aircraft by September 2013.
