Top bosses in the UK will have earned more than the average worker gains in a whole year by midday today.

The High Pay Centre think tank has labelled today 'Fat Cat Wednesday' - it claims the highest earners in Britain will sail past the average UK salary of £28,200 by lunchtime.

The group hopes to highlight the pay gap between average workers and top executives in the UK.

According to The High Pay Centre, the average pay ratio between FTSE100 CEOs and the average total pay of their employees in 2015 was 129:1.

"Effective representation for ordinary workers on the company remuneration committees that set executive pay, and publication of the pay ratio between the highest and average earner within a company, would bring a greater sense of proportion to the setting of top pay," the group said in a statement.

"After a year in which 'elites' were criticised for being out of touch and ignorant about the concerns of ordinary people, these pay gap figures confirm that there are dramatically different rates of pay at the top compared with what everyone else receives," it continued.

British politicians have considered introducing measures which would require companies to detail the gap in pay between its top executives and average salaries.

The group states that the median salary for top-earners is £4m in 2016.

UK Prime Minister Theresa May has said that curbing corporate excess will be made a priority during her time in 10 Downing Street.
