The systems of some of the UK’s biggest brokers are straining under post-Brexit demand

Some of the UK's biggest brokers are struggling to keep up with demand as investors rush to sell following the vote for the UK to leave the European Union.

Hargreaves Lansdown, AJ Bell and TD Direct Investing have all said they've had difficulties getting prices from market makers following the market open at 8am.

Some of the UK's banks put measures in place this morning to rein in trading as the vote appeared more certain.

Hargreaves has published a note on its site saying:

All Hargreaves Lansdown systems are working normally. Unusual trading conditions mean the stock market may not return prices for certain stocks in some circumstances. This could mean some clients experience temporary difficulty trading.

Disgruntled traders and market watchers took to Twitter to express their frustration.

same with AJ bell.
should ALWAYS be a market to buy and sell during market hours prices may not be favourable,

Hargreaves Lansdown update: @DannyCoxHL says share dealing has worked all morning but 'at times can't get prices from the market makers'.

Can't trade anything online with Hargreaves Lansdown today, makes it all a bit pointless really.

AJ Bell, which has £28bn of assets under administration, said trading volume was up by around five times this morning.

TD Direct said it was racking up triple volumes over an average trading day.

There has been a mixed reaction to how people are trading. TD Direct said customers were mainly selling, while Interactive Investor, which reckons trading volumes are 10 times normal levels, is forecasting almost two-thirds of transactions as buys.

Details of trading trends among retail investors will not be available until later today.
