After a tough few days the pound has strengthened slightly this morning.
Worries over the prospects of a no-deal Brexit contributed to a fall in the currency earlier in the week, and it hit a two-year low of $1.2439 at one point.
However, sterling has gained 0.25% so far today and currently stands at $1.2540. The move is partly due to a weakening of the dollar, after Federal Reserve chairman Jerome Powell hinted that a US rate cut could be on the cards.
The pound is trading a near-two year lows and analysts at Currencies Direct have been looking at the impact on Wimbledon contestants this year.
Phil McHugh, chief treasury analyst at Currencies Direct, said: "Given that March did not deliver a Brexit outcome, sterling uncertainty has increased and shows no sign of abating ahead of the October Brexit deadline.
"This means that when it comes to prize money, all remaining Wimbledon competitors will suffer from the pound weakening over the last few months."
For instance, Novak Djokovic would get £150,000 less than if the tournament had been held in March on the basis that he would convert any winnings into Serbian dinar.
Sterling has recovered slightly with the latest GDP figures, but will the effects last?
Neil Wilson, chief market analyst at Markets.com, thinks we need to consider the impact of the US Federal Reserve chairman Jerome Powell.
"Traders need to be careful as Brexit uncertainty remains the major drag on sterling, whilst the dollar is showing some resilience and could be exposed to significant upside risks if Powell today disappoints the market by not being as dovish as investors hope," says Mr Wilson
"Whilst economic indicators matter clearly, the ongoing uncertainty about the direction of the British government over Brexit it what is really driving the pound. We need to await the outcome of the Tory leadership race.
"There is a chance that the pound could find some bargain hunters if they feel likely winner Boris Johnson will soften his views on a hard exit on October 31st once he is safely installed by the Tory party and facing the realities of Parliamentary arithmetic and EU negotiators.
"His hard Brexit pitch right now is clearly aimed at the membership, so we should be careful about believing it all. Realpolitik will hit."
The pound has ticked slightly higher after that GDP data showing the UK economy grew 0.3% in the three months to May.
But it remains at lows for the year.
The FTSE 100 has opened little changed, down around 7 points at 7,529.45.
Sterling, which is heading for two year lows, is down a little against the dollar at $1.2451 as the Uk market opens.

Wake Up To Money
The pound is heading for two-year lows after falling below $1.25 and was close to its lowest level since April 2017 in trading yesterday
What's going on? Rebecca McVittie of Fidelity, told Radio 5 Live's Wake Up To Money there are concerns that if Boris Johnson wins the Conservative leadership contest that "we slip into a scenario of a no-deal Brexit and I think that, combined with some of the weak retail data we've seen, has caused the pound to wobble".
She says she does not see much in the short-term to change that but longer-term the forecasts for the economy are more stable.
Sterling has sunk to $1.2463 and €1.1124, its lowest levels since mid-2017.
It's been hit by worries about the threat of a no-deal Brexit under the next prime minister and a deteriorating UK economy.
